This move was too much for us - we're not willing to go without AMC (YMMV, of course), so, as much as we enjoyed Dish, we decided it was time to switch back to Comcast - the Triple Play pricing gave us HBO/Showtime/Cinemax/Starz/NFL/RedZone, internet service averaging 24Mbps, and VOIP, price-locked for 2 years at $159, then reverting to market rate (which is $209 for the same services). Plus, a $250 Visa gift card in 4 months!
If this were just a comparison of TV service, I would say that Dish has it all over Comcast in price. Add the other packaged services, and the fact that Comcast isn't even threatening to dump channels, and it was a fairly easy decision for us - keep AMC, save $100/month overall.
With respect to quality service, my inclination is to go with the company that screwed me the longest time ago, because somehow, someway, they all will screw you. Unfortunately for me, that means DirecTV is up after Comcast does it again...
Good luck and happy channel surfing!
