I have a friend who is looking for a projector and screen and I stumbled across these deals at Costco.com. Can anyone give me some feedback on these deals: Option 1 DLP Option 2 LCD Are these good prices? Which is better? He is building a basement part time home theater and will have solid light control. He really wants to have a screen that rolls away into the top of a bookcase or something like that but we havent found anything like that yet.
