Dave,
I have had Media one for about 2 years, and I still think it is grand. The advertised speed is 1.5M down and 500K up. I think I generally get about half. but for $40 a month, im still very happy with it.
From everything I have heard, compair the advertised bandwidth/$ and pick the better deal. I think it all comes down to how much do they have between the CO and the next big fish that is supplying their feed.
if 500 dsl subscribers all hop on and there is only 10M to the internet, they loose.
