I'm considering purchasing a projector on a tight budget. (wife says I have too many toys) I'm trying to stay under $3,000 for the projector. I have seen many used CRT projectors such as the Sony 12XX series for what seem like reasonable prices but I have no idea what to watch out for when purchasing used equipment. I saw a demo for a Plus Piano and was not impressed with the image. The demonstrator said that a line doubler would clean up the image but he wasn't clear as to how much cleaner it would be. Anyway, with the line doubler it would be over my budget. I keep hearing of the NEC LT150 but can't find anywhere to demo one. With all that, I have two questions. Can anyone tell me how the LT150 compares with a Plus Piano? Should I be considering a used CRT versus something like an LT150?
