I've heard of it, but a) I'm not sure if they have any in Canada, and b) I'm not sure if I could do it, since I'm nearly 19. =P(... That... Feels weird to say. It's true, but it just goes to show how quickly time is passing. xP)
I have checked out one form of it, I'm just not sure which. =P I know it's not NXT, although the place had NXT, we didn't get to use it. =P
I do get why it's so expensive; though; likely the main brick is the main cause there. =P
There is FLL in Canada, a Canadian team actually won 1st place at the world championships! (I was there). But unfortunately, the age limit in the US and Canada is up to 14 . . . And I aged out this year

The reason its so expensive is because its from LEGO. I cant think of any other reason. I can get an iPod Touch, which has 10 times the processing power, 100 times better display, and other stuff, for the same price.
