Greetings all. I am looking for some suggestions for a projector that will run, and hook up smoothly on the Air. I don't need top of the line, but maybe around $700.00 is in the budget so far. I want to be able to show keynote presentations, website demos, and maybe some shorter video clips as well. thanks, michael PS: I did some digging and wondered if the Optoma EP7150 was a good bet. The street price is around 800.00 (but I found a few that were around 500), and there is a newer model out now so the price should be dipping). 2.8 lbs, 2500:1 contrast ratio, 2,000 lumens... and XGA output. Anyone have any experience with this one?
