Are you fucking serious? All you do is play games yet you ruled out the DLP over the LCD because of the rainbow effect and "motion sickness"?!? If you did that after doing a side by side of the two sets, then you need a set of new glasses, or just get a 27" bowed out old RCA with coax input and call it a day.
Rainbow effect.... seriously, what a mountain out of mole hill issue against DLP. It's pretty much only legitimate purpose IMO, is to be used by the LCD projection whores in the Hi-Def forums to flame against the DLP. The only time I notice the rainbow effect is when you look for it on purpose (you have to bob your head around like an idiot), or you play DDR on a DLP set.
And motion sickness? MOTION SICKNESS? What's that got to do with DLP v LCD projection?!? Oh wait, I get it..... Because Grand Wega is so blurry compared to the DLP that it masks any chance of motion sickness from someone who's susceptible. LOL
