I have been on cable modem for the last 3 years. I just moved and had to switch to DSL-Net Racer.
DSL has been installed for about 2 hours now, and I find it is just as fast as my cable connection was.
I am not sure if it helps that I am about 2 miles from the central office or not though. The installer seemed to think so, as he made the comment that I had a very fast connection when he did the load test.
When I had Bellsouth DSL, the connection was not as fast as the cable connection back when I lived in Fla. That was why I had switched to cable.
