See if you can contact powertap in advance and have them ship USPS. I ordered this Hun to Canada in the summer (fantastic product, works great, but as mentioned the straight pull spokes may change at a bit more), but they shipped it UPS so I got dinged with their pirate brokerage fee, which is more than the HST that also has to be paid.

I just ordered the C1 chainring through Nash bar on Black Friday largely because they ship USPS. Turns out for powertap products they pass the order directly to them and powertap ships to the customer, so got dinged again :(

performance regularly sells a set of hed5 with this hub for 1299. it is an even better deal imo. I have one pair with g3 and also with gs and have been very happy.
