Help with which cable provider

[BirdManJr]

Ok we have always had just normal comcast. I had a 40 inch lcd
Well i got the 52 inch lcd a couple months ago. And we decided we want to get alot of channels and hd channels....Well i'm trying to figure out which way to go....

dish network...direct tv...or comcast digital

I'm looking for something that doesnt cost a arm and a leg..But gives a pretty good amount of channels...movie..sports...and cartoons.
Possibly a nfl channel. all that But with the hd also

Comcast seems pricey..thats why i just have basic.
but i hear stories of dish messing up in snow or rain....then i hear ppl say it doesnt...

Well which would you go with...and some info on why and how much you pay.

Thanks
