I'm thinking about a used CRT projector (can anyone lead me to a good reputable seller?) and I'm concerned about setup. Can I do this? I'd put it on a high table and leave it there, no ceiling mounting. BTW, do you agree this is a good way to go? Everything I've read says CRT is the best. LCD looks "grainy and blurry" and DLP makes me see rainbows. I only have about $2000 to spend and was thinking about a BG 801s, Sony 1272, BG 800, or possibly NEC 9pg. How about the picture? I've also heard I'd NEED a line doubler to get a 95" diag picture without scan lines. Can a PC do line doubling? Am I on the right track here? Thanks!
