I have cable, and if available, and you don't need to upload much stuff, I recommend it WAY over DSL. 80k/s is the low end of my download speeds. Sometimes I get 800k/s sustained on certain sites, and I usually get 150-350k/s. When I had DSL, I had nothing but problems. Plus, even with the relatively bad up speeds, they are still equal to what my DSL was (144IDSL), and far better than dialup.
Good luck either way
