I did a lot of research too! We were told that the best time to buy a TV is at the end of July/into August. That's when all the new model's of TV's come out so you can get amazing deals on last season's floor models and things like that. We got a 52'' Panasonic that was prices $1799 one week, then 1599 the next, and we bought the floor model the week after that for $999! Its a fantastic TV. I swear by Panasonic. Most of the electronics we own are Panasonics, and we never have a problem with anything.
So can you wait a year?

Probably not. HTH somehow though!
