Yeah I have been using it since Jan. and the service has been great. It costs $55 a month and that flat rate has all the phone features and free long distance for Canada and the US. I think it's $65 if you don't have cable tv and internet. The only bad thing that I know of it that calling outside of Canada and the US requires a phone card (which is cheaper anyway). It comes with 911 as well so you don't have worry about that.
You can check out the site it will give you more info then I know:
