I have Qwest 256 DSL (running about 300). I was with the local ISP Teleport, but they were consumed by Earthlink. Although national, I have not had many problems that weren't resolved pretty quickly. You're not going to save any money with DSL. You still pay the ISP $20/mo minimum and $39/mo for the DSL line.

I drool over the cable speeds but am now kind of glad I didn't have it available here. I imagine you have to show some pretty solid patience because of the conversion from @home to @attbi. Although inconvenient and frustrating at the moment, I'd still strongly consider it if they offered it in my area. I figure once they get the bugs ironed out, ATT has the horsepower to support the money losing cable ISP game longer than @home did.
