Want to buy a Home Cinema Projector. Advice Please

I am a newbie when it comes to Projectors. What i am looking for is a Projector , which will be mainly used for Movies and watching Sports on my Sky HD box. I need a short Throw projector as space is limited. I will not be gaming. And will watch some 3D content on Sky box. The plan is to project onto a 84 inch screen. i have been looking at the Optoma GT750 online. It seems to tick all the boxes but it is being marketed as a gaming projector. I'm not looking to break the bank on this Maybe around €800-€1200 all in. I will be watching this in a converted attic with black out blinds. 

Any advice would be most grateful. Maybe there is something out there that would suit my needs better than the Optoma GT750.
