The Royal Astronomical Society of Calgary will rent you a scope if you want to try before you buy.
http://calgary.rasc.ca/ The RASC has programs for young 'uns They do Build Your Own Scope programs as well as Friday Night Star Gazing Parties. They usually meet up at the Telus World of Science. There's bound to be someone there that can recommend a good scope. (In fact, just try to get astronomical society folks to
not tell you about their scopes!)
Tele-Optics in Calgary is a reasonable bet.
My personal fave is the Celestron Sky Scout Pocket Planetarium. Its not a telescope; it combines a GPS device with an astronomical database for hours of sky gazing fun. I got one for Christmas a couple of years back and I'm delighted with it. Meade makes a similar product, but I don't know what it's called.
