I've talked to the epson people and many of them believe if you have a little light to deal with, the 73c might be the one for you. It is cheaper and has 1500 lumens, the contrast ratio is 500 : 1. They seem the think that the picture is a little brighter. I haven't heart anyone mention it on this forum, but it is a new projector. Just a thought. Understand that the 100 is beter that the sony and brighter eventhough there less lumens on the specs.
Good Luck,
Joe
