Hi Tricia,
Ruth has supplied us with some great information. But, since you're curious, I have a Cyber Acoustics headset which I got at Futureshop about two years ago.

I may be at work right now...)
Anyway, if you're looking to find something locally, I'd suggest The Source (used to be called Radio Shack). I had a really great "gaming" headset which was very comfortable and reasonably priced. But, my kitten chewed through the cord!
I'd definitely consider you an Ontarionian, even if you're an "import"!
I see that you are in Toronto! I am planning on moving there next year (September 2010) to attend UofT for my masters degree!
