The one you own. I own Sony SAT-A4 and A3. They're the best.

Since you don't already own one, I can see your problem.

- decide which channel set you prefer. DISH's channel lineup is different than DirecTV's. You can find both listings on the web.

- If you can install it yourself, I'd suggest going to www.pricewatch.com and searching for "satellite". You may as well get the best price.

- If you're going to need someone to install it, I suggest buying from a local dealer, who can point you to a local installer.
