Summary: NEC UM330Xi - LCD projector that appears to be geared towards showing static computer presentations, where sharpness and edge delineation are more important than natural color reproduction or full motion video. Firstly LCD projector is more economical. If you can live with LCD, then that's probably better, less moving parts. I would say the best image available is the NEC LCD projector.
Pros: People buy NEC LCD projector, so its handy and portable
Cons: Projectors do not deal w/ sunlight very well
