Can't use normal projector as a ceiling fan is in the way and too valuable to have here in Az.

Now the decision will be do I want the ust on the entrainment center (similar set up to Russian guys video) or install it on ceiling close to wall it's projecting on? Pros to ceiling mount is kids won't touch it ever... if installed on the entertainment center I have to worry more about it getting messed with since it's down low. Cons is ceiling mount would be ugly from an aesthetic standpoint, whereas it'd blend in well on the EC.

120-150" would be so awesome. My 65 looks like a tiny toy on the wall (10 ft ceiling, 20+ ft wide). Playing 4 person Mario kart with the kids is painful with how small each quadrant is... but going to 150 would solve that fast lol.
