I've been working on this room since January. Hurt my back in March (not working on the room) and had to put it on hold for a bit.
Mitsubishi HC4900 projector
Peerless Projector Mount
Klipsch Front, Rear, and Center speakers
Toshiba HD-DVD player
Sony Playstation 3
100" screen DIY
I still need carpet and trim and a few finishing touches but you don't care about that once the movie starts.
Thanks to everyone here for your help and advice. Probably saved me some money along the way.

The answer to my own topic's question is ... YES!
I have gone ahead and bought one, and all I can say is WOW, to my untrained eye (i.e I dont have much experiance with projector performance) it looks awsome!
I have it in low lamp mode for the 5000 hour lamp life and am projecting a screen around 90 inches wide, the black levels look great to me, I dont think half the critisim written about this pj is warrented at all!
As for noise, what noise? Being a pc user im used to a lot of fans going constantly anyway. I dont even notice the PJs fans going over the din of my PC. The only time it makes any noise, which is whisper quiet, is when it powers up/down the lamp!
Video lag on native AND non native resolutions to my eyes/reactions is absolutely non existant! Game graphics are staggeringly huge, rich with color and have amazing 3D quality! When you jump off a huge cliff in a 3D type environment game you REALLY feel like your falling a huge distance!
Also standard definition TV through windows media center looks stunning!
To top it all so far i've only tryed projecting (temporarily) onto a bed sheet and now onto the plaster board wall which is to be plastered and painted over the course of the comming week, and to me it looks absolutely amazing dispite the ripples and blemishes in these 2 surfaces the image still looked rich and envolping so it will look even better on a properly painted wall or even a proper projector screen!
All I can say to any one considering buying a PJ in the near future is consider this one if you can afford it and also dont wait too long as this model has just gone out of production!

I have my projector ceiling mounted with a Peerless mount. My question is if the kids are upstairs playing on their WII should I be concerned with the vibration it is creating and shaking the projector in the floor beneath? Can this ruin my projector bulb, or maybe limit its life span?

Thankyou very much for the very positive and quick response Kajun! I was thinking the same about not comparing it to another PJs image quality. (It shouldn't matter to me if theres a better one out there as ill never put them side by side!)
Now im even more confident this ones the one to go for, for the money!
Does anyone else have any more suggestions? Also for the time being untill i have a proper screen set up im going to be painting the wall grey as this apparently helps bring out the blacks better. Im thinking a light matt grey for now, does anyone have any experiance on specific shades? Ive found a thread on avforums saying an aluminium paint mix is good for the long term, so I will look into that or a proper canvas screen once i have the PJ in operation and im used to it.
Thankyou to everyone on this forum youve all been a big help with the wealth of important information you are all generating on here :)

Firstly, thankyou in advance for any advice you can give me on this, I am new to Projectors/HT and this is my first post, but have been gameing and building PCs for a while. I have recently built a PC capable of running modern games in 1080p at good framerates and now wish to look into investing in a good quality projector for PC gameing on a 100" screen. I have decided (for the moment) on the Mitsubishi HC4900.
I have been reading around the site and have found some good information on the key factors in PC gaming on a projector. I now just have a few questions in general but also specific to this projector if anyone has any experiance with it or a similar one.
1. My main concern before blackness/brightness levels is video processing lag time. Will this Projector be a good performer on this factor if it is run at its native 1080p for pc gameing such as first person shooters and other 3D environments. I've read that non native resolutions can produce a 5+ frames per second lag in games and possibly make them unplayable, but running the game at native will reduce this significantly.
2. As i mentioned in question 1 blackness qualities and brightness levels are my second concern. On this factor ive found that people are saying a projector with a contrast of 4000:1 or more will be ok and the HC4900 has 7500:1 so im fairly confident it will be ok although I have read some people saying the blacks aren't as good as other PJ's (particularly DLPs) but as this is my first im hopeing my eyes wont be so critical. Also my room light levels are 100% controlable but I would like to have some ambiant light somtimes, will this PJ be able to cope with a 100" screen at 3.5 meters, I've read it can but does anyone have experiance?
3. This is an LCD projector would a DLP have a noticable difference in picture quality?
4. I intend to project onto a newly plastered wall, can anyone suggest a good paint/color and finish for the wall? Im going to be repainting the rest of the room with a color that won't reflect to much light but at the same time not make the room feel tiny.
5. The room the PJ is going in is unfortunately fairly dusty are there any ways to prevent the projector from getting a dusty image (i've read this can be a problem), other than cleaning the filters regularly which will be done of course.
6. Are there any other factors I should take into consideration?
My other reasons for going for the HC4900 are it has a really good lamp life (5000 in eco), the genuine lamps are half the cost of some others, it claims to be quieter than a lot of others and from looking at its specifications it also claims it will be able to produce a 100" 16:9 image at around 3.5 meter throw distance which is about all the physical throw distance from the intended screen location I have.
Thankyou again in takeing the time to answer my newbie questions.
