ISP: Bell Sympatico High Speed ADSL
Satisfactory: Very Satisfied
Pros: I've purchased a 7mbit connection for $45 a month and I receive a solid stream of 5.2mbit. It's a very reliable service, rarely has problems, and if there are problems they also have a very helpful technical team.
The other big competitor in my area is Rogers Cable, which usually sucks and has huge downtowns. I remember my teacher saying it took him 3 days to download 300mb at one point.
I prefer ADSL anyday, because it is a constant connection uneffected by other users in my area. The factor determining your speed is the distance from their network, which I'm fortunate enough to be close.
Cons: No faster connection is offered for my geographical location. My service used to have unlimited bandwidth usage but was capped at 100GB about a year ago.
