I consistently get 25-30Mbps down and 7-10 Mbps up with Comcast and my own DOCSIS 2.0 compliant cable modem (Motorola Surfboard SB5101). It's better to buy your own cable modem as I've heard the one Comcast supplies or sells you isn't as fast.
I'm quite happy with Comcast with regards to the speed. Removing splitters in your cable line can help with speeds as I understand it, just a tip.
I'm not saying I like Comcast as a company at all but they are the only option in my area for this high of a speed. Verizon FiOS is not here yet and DSL is slower.
I do not have an opinion on the TV service as I only use Comcast for internet. I get all my HDTV over the air, which works well for me.
