honestly, if i remember correctly, I believe i picked up the 7000 about a year back, and absolutely love it and don't regret the purchase (slim 3D LED 55")
however, I look at the market now, and stuff like that can be purchased for less then half the price i picked it up for now. My friend just picked up a 60" LED for about half what i paid for my 55" and it's got about the same features, minus the 3D
my advice is, get the size you want, and the options you need. Don't look at the top of the line ones for no reason, don't get suckered in. The tvs that are a year old are just as good as the ones now, I don't need WIFI on my tv, I don't need 3D on my tv. just figure out what you do need, and go from there.
I basically bought top of the line for one reason, photo editing. That was my whole reasoning for taking the road I took, otherwise, i would have gone for something simpler and half the price.
besides, get something cheap because you and I both know, you'll be replacing the tv within 2-3 years anyhow with something newer, bigger, and more features that don't exist now
