I was spending about $150 for the Triple Play with Comcast and just switched a couple months ago to Verizon Fios HD, which is about $103 with the tax.
It's good for us-- we weren't watching a lot of TV. I know that with Comcast I got a bunch of extra channels like Encore and stuff... seems like I get fewer channels now. But it's ok for me, because I never watched them much, anyway. There also appears to be fewer "On Demand" Free movies available.
I do think it's more reliable-- I was always calling Comcast to "reset my signal", but never have to do that with Fios.
We also got a $300 Visa Gift card for doing the 2-year contract. I think it was definitely worth it for us, but if you like to watch a lot of channels, it might not be for you.
