The "internet" told me I needed at least 3000 lumens and those were running $1,000 so I took a chance on this (see bottom of linked page) for the pumpkins. I liked it so I much I bought another and then a couple of months later bought a third one. When I went to get another I couldn't find one from the same Ebay vendor and was scared to try somebody else. $170 seems pricely but it does every thing I needed it to do (e.g. HD video, sound, plays from a thumb drive). I've seen other posts where other were getting good results with MUCH cheaper devices.looks cool What projector are you using?
