By the way, some local dealers will install projectors you buy elsewhere, but, don't you worry, if they are doing your room, they will almost certainly recoup most of the savings you made shopping online. It's logical, and it's fair. Also, if you buy your projector elsewhere, and there are issues with it, the local dealer, who primarily works on an hourly basis, is going to be charging you for all the extra time, working with the defective product. When you buy the equipment directly from them, their obligation is to check everything out in advance, so if, say a projector is defective, they would be expected to replace it, without charging you for the lost time. Ultimately you make the call. OK, time to summarize - remember, we only tested the Home version, but, from a technical standpoint, the two projectors have the same "engine", so even though they have different menus, and some other differences, from a performance standpoint they should be close to identical.
