Want a Projector, but have questions?

[funkyshooters]

Hi all. My HT currently has a 72" Toshiba DLP. I have the room and have always wanted to do it... I am going to move to a projector with a 120" screen. Problem is I am new to the projector world. I have been doing A LOT of research here, online, AVSForum... I think I am going to go with the Epson 6500UB. Seems like I will get the most bang for my buck there... Below are my questions and I would appreciate any help someone can give.

1. What do you think of the Epson 6500UB.
2. For the 120" What should I look for? I found an Elite screen here http://www.projectorscreenstore.com/...E24-39932.html

Is there something else I should look for in a screen?

3. And prob. the most confusing to me... Throw distance! I used the calculator at Project Central and got some good numbers... I have a 13' 4" distance from screen and a 120" screen. It says my zoom will be 1.86x. Really I don't understand the numbers... Will the zoom lower my resolution?

Thanks for any help!
