I can verify that there is always at least one dealer at the Easter show with a table full of bits, including sight parts, but that individual is looking to get much more than what Numrich charges for the sight. The trick with Numrich (one of the few US dealers willing to ship to Canadaicon ) is to order a bunch of items to get close to the US$200 max order limit for Canadians in order to mitigate the US$25 "handling fee" they tack on for each order.
