I just picked up this tv today since I have been shopping around for a few weeks:
Sam's Club-*$797 after $100 Instant Savings* 40" Sony LCD 1080p 240Hz HDTV
For less then $800, it has a boatload of option, the most of which was having a wifi or ethernet connection to my home network. 1080p and 240hz refresh isn't to shabby for this price also. I understand the reason some have for staying away from 1080p. This is my 4th current hd set and 2 of them aren't 1080p since they are for mostly TV watching. What I don't get is that some think that 1080p resolution is a fad or something. The basics are that you are buying a TV with superior resolution, just like a computer monitor. It is true the 720p and 1080i's are cheaper, but its mostly because they aren't as good.

Also found this to fuel the 720p vs 1080i topic
