What service are you using?
For 5 HD movies a month (about 20GB) and some game downloads (say another 20GB) you should be able to get by with a 60GB Express package. Given what you're paying I assume you have Extreme - so you should have plenty.
You should know that TekSavvy (and almost every other DSL providers) will be going to a capped/usage based billing system quite soon as the CRTC is now permitting Bell to charge third parties for usage. The only providers who can get around this are the ones with their own equipment (not many, and not TekSavvy).
OK SimplePanda, since you obviously feel that you understand my download usage better then I, let me spell it out for you.
Movies - about 2-3 per week @ 4-10 GB so anywhere from 8 to 30 GB
Games - GTA IV (15.6 GB), Tales from Liberty City (16.6 GB) = 32.2 GB for one game. Borderlands 12.2 GB. That's 44.4 GB for two games. Dirt 2 (10.5 GB), I'm now up to 54.9 GB. Oh, and I have more then one computer that I like to play games on.
I could go on, but I'm sure you get the point.
Now perhaps you are able to "get by with a 60GB Express package", but I am not.
Warning Rant Ahead!
The caps, throttling and general dirty network practices of the big ISPs on the surface might seem to be just annoying, but in fact they are stifling innovation and manipulating one of humanities greatest resources for there own petty profit.
Ahh, I feel better.
