Great guys, thanks for all of the valuable information. One last question though: Do I need a dual or triple lnb dish?

Hey everyone, I'm extremely green when it comes to DVR's (if you can't tell by my name) and am curious what the most recent DirecTV DVR models are. I would like to purchase one through someone other than DirecTV so I'm not locked into leasing the box, but I'm not sure what model(s) to look for...
