I have been sat free for a few years now, and have been using GCL to watch Sens hockey. So far this year, I am surprisingly impressed with GCL.
quality has been good on all devices that I am using ( PS3, roku, ipad, comp).
also, I have not been blacked out of any games, I have had all of them so far.
if you have some services with Rogers, you might have a free subscription until the end of the year, so it is worth trying out.
cheers,
Spielfreak (PSN)
