We have Comcast digital cable. There are four of us paying for it, so the $100/mo. for digital cable/cable internet is reasonable. We've had problems with charges a couple of times but they've always straightened it out. We've never had a problem with our box. We've had it for 2 years now. We had to call a service tech out once at our old place due to some reception issues we were having (apparently due to construction on the next street over, or so the tech said on his receipt
) and the guy checked all our cabling and connections, replaced our splitters, and didn't charge us (Comcast had said if it turned out to be an issue on our end, we would be charged for the service call). We've had similarly pleasant experiences with the cable guys that have hooked up our service. One of the factors playing into that might be that my guy used to be a cable guy, and so we're both extremely polite to the techs.
I don't really have a choice in service; Comcast is pretty much the only game in town.
