Hi guys, my first post .
I have a 20' x 12' room for my cinema project and need your help.
I'm totally confused with the projectors and jargon so I'll ask you guys in the know.

I'm looking for a HD 1080p projector (price range about €1700) have my eye on an Infocus X10 (any good?)
I need to hook my PS3 up to it.
Also need info on mounting it and screen type (if any) or might just paint......

Any help appreciated .....

OK then.......
I've read all the reviews and have come to the conclusion that the X10 is HUGE...lol.
Gona spen a bit more and go for what I wanted to begin with but couldn't get her indoors permission for, Sony VPL-HW10.

So as it stands my cinema consists of the following....
Sony VPL-HW10 - Being ordered on tuesday deliver by friday.
Sony HT-SF1300 Cinema System - received friday.
Sony PS3 - OMG i love my ps3
and a big empty room to rip apart and do with as I please.....
The effect I'm going for will be HOPEFULLY like this

In a brown colour and without the blue furniture and I have some lazyboys already.

Anyone have any ideas on where I can get the ceiling lighting from??
