A friend of mine who was on Sympatico did some research and came up with IStop -
http://www.istop.com/residential.html
Reasonable prices for 15GB with lots of off-peak (if you disconnect and reconnect before raping the system so it registers you as off-peak), and the modem rental is cheap (but he bought it for $149). At least it's $CDN!
Also, a static IP is available if you run servers and such.
I'm on Rogers so I'll have to make a switch eventually, but right now I'm making the best of it
