Please don't jump on the LED bandwagon by buying a projector off Ebay... please don't... that's how you jump onto the 'buying junk from random mainland companies' bandwagon. Most of those mainland manufacturers that sell cheap projectors on Ebay, not just LED, but standard projectors of all types, use really cheap materials for build, and have horrible QC, and limited to no certifications, brandless (shameless), and therefore making the projector extremely cheap.
It's like playing russian roulette, except instead of one bullet in the 6 pin chamber, there are probably 5/6 loaded. Don't test your luck with a brandless projector, please don't.... save yourself the trouble and frustration.
I Love Apple, BenQ, Samsung, and Acer Products = )
