Wich is better? We just got the letter in the mail stating that Digital Cable Modems are finally available in our area after a 5 year rate. But, we also got the Cablevision bill a day later, and found out we're paying close to $70 freakin' dollars for basic cable, + HBO/Encore. Is it really worth signing up for it, or is Satellite Cheaper and better both ways? Also, when you get access to digital cable, does that mean Digital TV is available as well? I.E. More Channels? THanks!
