So I am trying to decide between a 46 or a 52 inch LCD. Any pros or cons with one over the other? My room is just over 12 feet for the viewing. I am upgrading from a 42" and always thought that a 50 was the way to go, however the 46 seems fine. I was wondering if there were any downsides the the larger screen as far as screen refreshes, etc. I figured maybe the 52 might be slightly slower due to the size. How about things like picture stability, high speed action shots, etc.

Also if anyone knows much about these two tvs I would love any input. I am trying to decide between the Mitsubishi Diamond LT-46244 or the LT-52244 (46 & 52 respectively.)

Thanks,
-Tony
