Tailgate TV advice

We've had a spot on the boulevard for about five years now and are thinking about getting a TV set up since a lot of our games are night games this year. I've seen a lot of spots out there with TV's on stands hooked up to what I assume are satellite receivers. I just wondered if anyone had suggestions on where they bought their equipment (Best Buy?) or what satellite units work best. About how much would the budget be? I've got DirecTV at home so not sure if that's just something you can add to the account or not when you buy those receivers. Anyways, thanks!
