Also you might want to look into musicians friend, they have great deals on gear and are great to deal with.
As far as music stores in Calgary, I like to deal with Long and Mcquade. I checked their website, and the only cymbals they show online are Zildjians, and mostly of the K variety. So much for staying in the 100$ range. Their cymbal shop though has lots to offer... different brands/lines/price ranges... although its been a while since Ive been in there and cant remember there being much to offer in the way of Paiste's other than Signature Sound Edge hats... and effects stuff.
Im a big Sabian fan myself, and for entry level cymbals the B8's, B8 Pro's, and XS20 series have great value and can be bought in packs. Sabian also came out with a new line called APX. I havnt checked them out or played them, but since they are a B8 composition, I would guess they are reasonably priced. The bonus with Sabian/Zildjian cymbals is that they are cooked in just that special way that makes them very durable. Paistes... not so much.
You can probobly pick up a B8Pro pack with a crash, china and splash for around 200 bucks? Something like that? For sure you could get a 16 - 18 inch B8 crash for under 100 clams.
