I just want to add my 2 cents. I went from a dalite white screen to a greywolf II. my sanyo z4 projector is mounted on a 7ft ceiling and the actual lens is at about 6'7" from the floor, my throw is 12'4 and I do not have any complaints with the greywolf II. it is definitely brighter and more contrasty than the dalite. actually the results are startleing. I do have some ambient light issues,white ceiling, tan carpet,leakage around the drapes, thats why i switched over. When you state that ceiling mounts dont work with glass bead screens. you really need to specify "how high is up" at 7ft I have no issues and the picture is only slightly brighter standing up than sitting down. I still get a brighter picture with my ceiling mount and the greywolf than I had with the daylite. I do however acknowledge that the higher you raise the projector the less benefit the 1.8 gain will give you.. you however you will still have a more contrasty image with the grey wolf then with a pure white screen.

i'm having an issue with my PJ randomly shutting down recently after i changed the lamp. it has never been an issue before, but it's doing this pretty regularly now. my PJ is the sanyo Z4 and is 4 years old. no smokers in the house, kept in a very low dust and cool basement. one thought i had was that the place i ordered the latest lamp from gave me a bad lamp. i ordered it from electrified.com through recommendations i got here. the lamp that i got had a few noticeable differences from the one i replaced. instead of a thin metal screen vent(?) it had a hard plastic screen with fat holes. one other thing i noticed is that occasionally the new lamp will click a few times before it comes on. any thoughts on what else could be the issue? thanks in advance, matt

Over the last few months I've begun to notice a "hot spot" on my screen. In other words, the illumination isn't even and I can clearly notice the projector beam on the screen. I thought it might be the bulb and changed it, but the hot spot became more pronounced. It is possible that the hot spot has always been there I guess, but I sure wasn't aware of it before. Has anyone else had this problem? Is there any adjustment I can make to fix it? BTW, I have a Sanyo PLV-ZR mounted on a shelf at the middle of the screen.
