Looked at DSL, not for us right now. Limited availablity in the area we're concentrating on, not enough margin to make the investment worthwhile. We are looking at wireless for the area, and then go head to head with the little DSL that is offered (no cable here either).
For wholesale internet, went with startanisp.com. This isn't the StartAnISP person here - there's is yourownisp.com. They seem pretty reasonable as well. startanisp.com had the features we wanted, and was very willing to talk about the business in an open manner. Volunteered alot of information. They only carry Qwest which is about 2900 numbers nationwide. But they had access in the area we are targeting which has 1 other isp really, and VERY limited DSL as the only other alternative.
