The OP seems to move around a lot. You'd think having a Comcast alternative would be on the must-have list for a new home by now. I guess he is moving into 20+ mile radii with no ISP other than Comcast?
- My DC apartment only had support for Comcast
- My NY apartment only had support for TWC
- My Portland apartment only has support for Comcast
In every instance there was only two real options but because of the way apartment complexes work you really only have one option. It doesn't get better if you own a home either. I know plenty of homeowners that are stuck with Comcast because the alternative "isn't available on their street"...for whatever reason.
