Direct Tv, Flat screen, HD, DVR questions

[scott8]

Thought I might find help here.

Just moved into my new place and I think that tomorrow I'm going to pick up my first ever flat screen.
Then I want Direct TV, mostly b/c of the football package, but the cost for Direct TV with DVR is somewhere around 699$ not including the package.
Does anyone have Direct TV with HD and is it worth it?
Anything I should know or look for in a flat screen?
I have had DVR for a year and don't think I could go back to life without it - I am a slave to the tv, but at least with DVR it can be on my time.
Any advice with the flat screen, direct tv, or anything else would be appreciated.
