The new Panasonic PTAX200 is about the brightest of the new breed of lcd projectors at 2000 lumens.
It also has a refresh rate of 5ms and a special gaming mode, and so would be ideal for games.
Don't think you will get a hold of the PTAE1000, as I hunted high and low a few weeks ago and gave up (check my thread).
Don't know how the AX200 would compare to your existing pj, although this is the new bang up to date model, why not have a demo ?
I would think you'd be impressed
