How much does that run you? Has the monthly changed much over time? For residential at least, Comcast is known to give you a sweetheart deal for the first 12 or 24 months, then balloon your monthly.
I pay for the very basic speed, 16mbps down 3mbps up. I get pretty close to that most days. It costs me a bit over $70/mo after taxes for just Internet access. Comcast does offer phone and TV bundles that include limited-time deals, but I didn't go for that and this price hasn't changed on me in 3 years. There's no monthly data cap and the connection speed is more reliable, which is why I'm happy.
I did have to pay a significant amount of money to get it set up. I don't remember exactly what the price was, but I believe it was in the neighborhood of $200 setup fee.
It might be a ripoff, but it's the best I can get. You learn to live with what you have. Would I like cheaper, faster Internet? Hell yes. Can I get it? Nope :(
