Yeah I get what youre saying. What you also have to realize though is, the cheaper TV's use cheaper components as well. Its not just what you see, its whats inside also. Obviously up to you what you want to spend but.....
Cheaper components are big one for me. A sony is going to last significantly longer and look better than some cheaper TV like that. Youll need more repairs and hastle....You have to weigh some of that as well.
One other thing you should consider also is, a 32" is fairly small and youll see less of a difference. If you go look at the 47" and compare to other brands of similar size, youll see what I mean.
Anyways, just trying to help you out, so down the line when the TV starts to go out fairly quickly and youre not kicking yourself for buying the "cheap" one.
I guess im spoiled from buying a 50" pioneer elite and 32" sony S3000. Both of these TVs look amazing. When it comes to TVs for me, its not always about getting the "cheapest" one.
