hello all, i'm new here so take it easy on me. i'm going to be purchasing a t.v. saturday, i'm looking for a 55-57 inch 16:9 rear projection set. my budget is between 2000.00 and 2700.00 i'll be shopping at bestbuy and circuit city. i know i need to check out how the set displays 4:3 sources, but what else are some important things to check for? this t.v. will be my primary set, picture quality is a must sound is'nt as important. if anyone has any advice on paticular models to look for/avoid i would sure appreciate it, thanks paul. p.s. i'm looking for high def.
