I am quite thankful to the two replies I got for my needs. I checked out so much for WT610 and Pluribus. In India, not even one HP personnel had ever heard of Pluribus. I,inevitably, ended up with - "P for Poland, L for London, U for Umbrella......." with each one of these people, which was followed by a looooooooooooong pause and in two cases, the line was cut off immediately(I guess they don't record calls here for monitoring purposes, or the girl had already found a new job waiting for her). Anyways, Pluribus search has ended in abyss,with me sending radio signals into deep space, waiting for a reply that i will get in another thousand million years(probably). Is there any place on Earth that I can find Pluribus in civilised ways? And the NEC people in India found in me a nice Guinea pig. They started promoting NP4000/4001 to me. It hasn't escape my attention that the NP4000 is substantially more expensive than WT-610. The NEC here also talked of WT615(I guess that's waht they call WT610E here). I wonder how good these two projectors are for my requirement. Can someone suggest me something about it? And due to my lack of knowledge I requested NEC to help me with the Screen also, one which would help me maximise the output. They talked of some DAYLIGHT screen(ROCKET SCIENCE has fourteen alphabets in it). He also told me that a 4feet by 6feet screen of this screen will cost me around US$2500(Isn't that the going rate for TITANIUM??). Can someone also help me with this screen thing? I need a screen size of around 35feet by 15feet(manufactured on Earth, not imported from Pluto), and sounding reasonably priced.
