This is the opposite scenario (Candian seller, U.S. buyer), but I recently purchased a piece of equipment from a Canadian seller who shipped the item to me in the U.S. from Canada via UPS. It got held up for about a week in U.S. customs. Although the seller carefully packed the items, U.S. customs no doubt didn't use the same care when when opening, inspecting, and repacking the item. Based on this and my other experience with U.S./Canadian tranactions I'm going to pass on further such opportunities. Politically, I like to think of Canadians as brothers and sisters, but the costs and hassles associated with the practicalities of shipping equipment across the boarder seem to provide more downsides and risks than upsides. If you don't mind delays, extra duty costs, and mediocre handling of your equipment maybe it's worth the effort. To me, it's the issue of non-audio people inspecting and repacking pristine and delicate equipment that was carefully packed that pushes it over the edge. I'm going to avoid it in the future.
