Hi again!
I'm from Canada too and I've got my 7300 (do not jump and buy 635, although is a good receiver,but 7300 is THE BEST!)from "etronics"-they work with Borderfree(part of Canada Post), you know the total cost in canadian dollars(NO DUTY FEES-call Canada Customs and you'll see)at the check out on line.Amazing service!
Good luck!
Octavian
