I think that depends on quality. A gigabit fibre connection is pretty damn good. Far faster than most households need by a good magnitude. And the fact that most places offer such a thing for under $100 is pretty decent.
The real question is how much does it cost to get a 10mBit connection. It's been a while since I've checked, but I'm pretty sure that it's also pretty close to $100, which is definitely a problem.
