Alternatives to DSL and Comcast?

So, it turns out that DSL/T1/etc. are not an option for our address. Anyone in (or formerly of) our area have any other options that we should look into? Is there any highspeed internet with any level of reliability besides DSL and Comcast?

I loathe the idea of continuing to use Comcast at this point, but I’m fearing that (as it was when I moved in), it’s our only option. 🙁
