Hi there. I've seen the Aim 75" TV at pnp and I was very impressed, looked damn good to me. I compared it to other sets that were on display there and I could not fault the picture quality, but then I'm no TV expert. I guess most people will tell you not to buy it as Aim is a pnp brand and therefore can't be any good, stick to Samsung, LG etc. As a second TV for that price and size, I was tempted myself.
I know you don't want to go out unnecessary but you must go and see it for yourself.
