LOL, Love those, especially the zombie and blood images, gets me wondering if I can do a setup like that. Your probably looking at a business type pj for that price and lumens, most will be less than 1080p and you might want to see if any of the cheaper PICO type pj's might suffice, as they'll be a little smaller, but will produce a smaller image overall. Do a search for under $500 over at, http://www.projectorreviews.com/projector-search.php
and look at the lumens specs. Man, those looked awesome, thanks for bringing 'em to my attention! I usually get some decent stuff up for halloween, but those are over the top!
