I was looking at microscopes the other day, cause I have no life and nothing better to do.
Not to be condescending cause I'm sure you know this, but getting one from the US seems a much better bet.
This one I was looking at is $170USD from Amazon, or $270-300 from anywhere I've looked in Canada.
The only local brick and mortar shops I can think of are the Science Centre's gift shop and that telescope place in Didsbury (?).
