a few years ago, my roommates bought a commercial NEC CRT projector (much like the one pictured below) on ebay. I believe they spent $1500 for the unit, which was 15 years old and retailed for $25,000k to $30,000k (new) when it was still on the market. I told them they were crazy, that there was no way the thing would be selling for that cheap if it was in working order (as described in the listing).

Sure enough, when the behemoth arrived, it was a 250lb coffee table-sized lemon. when powered on, it kept saying (error XXX - Fan 3)... then it would shut itself off. What is funny is that after replacing all of the fans with cheap computer case fans, the error screen went away.
I remember spending days, literally, calibrating that projector. After about 30 hours and a few cases of beer, I was completely blown away by the picture quality. We had a 300 inch screen going on a wall that wasn't a whole lot larger, and a sweet SLI-gaming rig hooked up to it.
I think I watched "finding nemo" 20 or 30 times over the course of a month... not because I even care for the film, (i hate kids movies), but because the colors were so incredible. I have still yet to see a display that I thought looked more natural, including a megabuck DLP projector I saw in a private theater a few years later.
I definately think you are making a wise choice by going with the CRT. Once its properly calibrated, you will have no need for 3D capability.
