I am going to buy either the Tosh 57HX81 or the 65HX81. I will be sitting approx. 10' from the screen. I looked at both in the store, and the 57" seemed a bit small. Don't know if that was because I was in a big showroom or not. $$ not the issue, I just don't want to buy the 65 and then regret it. Need your opinion please, because I'm having the wall unit built soon to fit the set I decide on. Thanks.
