I may begin looking to upgrade to an HDTV (if I can save up some green). I watched a football game on one awhile back, and it was like I was standing on the side-lines. Does anyone have any knowledge or any ideas? Brand, type, technical info, or so forth? All this new technology is tough on an "old man"!

I am on a satellite dish, and I know I have to upgrade my receiver too.
Thanks in advance for any help!
