You do not want dsl. Think about the cables which the signals are transmitted through. DSL uses phone line which is usually 3 strands 20-30 gauge wires (maybe even smaller) to transmit your data, cable on the other hand is 40-50 strands of thicker cable. The infrastructure of most of americas phone lines is pitiful, some of those phone lines ran through the house and the ground are older than I am.
I have timer warner 10mb cable internet which I pay a little over $50 a month for. We have 3 xbox's all connected to live, 2 laptops, a desktop, and 3 phones all connected to our internet and we're able to play all 3 xbox's with zero lag.
ATT&T uverse is still dsl internet, it just has a few more bells and whistles.
