I would check out the new BenQ HT4550i which is expected to ship in April. It's got a 4-LED light engine so no bulb and better colors, 3200 ANSI lumens, low input lag for gaming, horz and vert lens shift for easy placement, etc. Looks like it will be a real nice unit for $2600.

And while it is DLP, a 4-LED light engine doesn't use a color wheel so rainbows shouldn't be an issue. Another advantage of the LED light engine is instant on/instant off.
