I used Sonic when I lived in SF. Dane himself tweeted back when I mentioned them, and their customer service has been super transparent (you can see on their support page [1] how many calls are on and waiting), extremely honest and helpful, even for a nerd like me.
Yes. Love these guys. Every time I call support I get to talk to somebody with both knowledge and sense. In sharp contrast to when I had AT&T DSL or have to deal with Comcast for friends.
I have nothing but admiration for these guys.
