Hello - After a lot of research I bought a PB2250 from BenQ. Great little projector and great price - but I can't watch it!!! Turns out I am one of those people who suffer badly from the 'Rainbow Artifact' effect and after about 10 minutes with this projector I have to leave the room. The shop where I bought it have agreed to exchange (for a small fee as there is actually nothing wrong with the projector) - but what should I buy instead? I want XGA, I want small & light, I want bright, I want good for movies and presentations, I want about the same cost, and now I guess I want LCD rather than DLP. I a looking at Epson EMP 750 as an alternative although it is more expensive. Does anyone have any suggestions
