You can always do the HD advantage deal at Best Buy for any TV over $999.
Basically it lines up likes this.
You can get up to $600 off any TV over $999.
Sign-up for DTV - get $300 off TV
Buy an HD-DVD or Blu-ray player - get $100 off TV
Buy any installation - get $100 off TV
Buy at least $500 worth of Home Theater stuff - get $100 off TV
So you say, what if I don't want DTV, a HD-DVD or Blu-ray player or $500 worth of Home Theater stuff or an installation for that matter. Well here is where you can use a loop hole.
1. You can always cancel the DTV service the day after you sign-up and you won't get charged a dime (plus you still get the $300 off the TV).
2. You can return the HD-DVD or Blu-ray player and still get the $100 off the TV because the discount is taken off the TV.
3. The installation is a bit tricky to return because most of the time the installation will be packaged with the TV. So my advice is just not to sign up for an installation (you will still get $500 off the TV in the end).
4. With the home theater stuff, just return it a few days after you return the Blu-ray or HD-DVD player. The $100 discount on the TV will still be there because the discount is off the TV and not off the home theater stuff.
These are the steps that I went through and I ended up getting a 42" Panasonic PZ77U and an 80GB PS3 for $400 total (it would have been a total of $900, but the local BB made a mistake and gave me a free Blu-ray player that I then exchanged for the 80GB PS3).
