I'm a wannabe Conch, so I'll give you an opinion :11:
We have Dish, and it's great. I echo Renee, and say GET DVR!
I think part of the issue with Dish is how good is the signal. We have some very serious thunderstorms in the Mnts during the Summer, and I can count the number of times we've lost signal on one hand, however it may be different in FL.
If you go with Dish, and you are a NEW customer, shop around, and get as MUCH equipment for the X number of year commitment as possible. My buddy did NOT take this advice, and is now looking at about $500 in equipment upgrades because he did not want to commit to a package that he upgraded to after just a couple months of barebones service.
My buddy up the road has the HDTV with Dish, and the reception is incredible. However it IS expensive! However it's even MORE expensive if you get the standard FREE installation, and then go HDTV later.
I can not comment on FL cable, but Comcast in our area has VERY BAD customer service. Dish OTOH has some of the best customer service I've ever encountered from any service provider.
