No offense taken. You are quite correct that a DILA is a much better choice for 99% of home theaters than a used ILA projector.
These older projectors were never intended for home theater use however and were instead geared towards commercial uses such as trade shows, concerts, flight simulators, etc. If I had a huge HT room w/ an enclosed room for the projector and a larger budget for operating costs (power, lamps, etc.), one of these used M200 projectors would be hard to turn down. Imagine the brightness of a G20, but with much better (CRT-like) contrast, higher resolution, no internal scaler artifacts and a complete lack of pixelation.... all of this in an "obsolete" technology lol.
Don't get me wrong, I love the new DILA's. But, DILA's haven't yet come close to surpassing the older ILA's in PQ. The new Q-XGA panels will close the gap however.
