Both my mom and dad (separated) got this service about a month ago. Whenever I go over there I check it out. It's very good. Haven't checked ping times or upload speeds, but downloads are the promised 10mbit if you connect to a good server. Customer service is also exellent and when you call with tech questions there's no wait or anything.
Also, you can elect to have them supply your Phone lines and cable TV. Both are great deals (with the phone you get like 100, 500, 1000? minutes statewide long distance for free every month). The TV is great... they offer something like 290 channels. The total bill with EVERYTHING (my mom got the works) is $146 a month for her I believe. My dad didn't get the phone and only got some premium cable channels and he pays like $91. When signing up, they have extra deals if you buy more. Like since my mom got the works she also got a lot of discounts on the price which brought it down.
It's definitely a great deal. Too bad my wife and I just moved into apartments, apparently they're not hooking apartments up just yet =(
