Help me pick a projector.

Hello,

I just bought a new house with a nice big basement. I am going to build a theater room. Need to get a projector.

My room is going to be about 16x26 and perfect rectangle. 7' ceilings, maybe a little more.

I want to get a screen as big as I can. 120-150" or even more.

My audio gear: b&k ref 50s2, b&k av-5000s2, DCM time window 7 main. Dcm tfv-10.0 rear and side rear. Dcm Surroundscape center. PS3 as source and a Sony BDP s500. Thiel smart sub.

I am going to first try doing a screen on the drywall. If that doesn't work, I will buy a legit screen.

There will be zero windows. So it can be super dark. I am not a videophile, but I appreciate a good picture. I have a 60" Panasonic plasma in the living room.

Thinking of a emotiva umc-200 possibly. One question, is it worth it? For hdmi and modern formats vs analog out from my sony BDP.

My real question is the projector. I need to grab one. I have 1500 in amazon gift cards to shop with. I don't mind a refurb and want good quality. I also want easy setup since I am doing it myself.

Any suggestions out there for my projector or thoughts on the processor?

Thanks!
