I ordered my HK 3.0 water block from there, no problems. They shipped first class mail which is cheap(like $10) but there's no tracking and maybe no insurance. It showed up OK though. I didn't get dinged any taxes or duty but that's Canada Post's "slip". I find that most orders under $100 get across with no fees at all. Not worth the paperwork I guess. But it's really luck of the draw and there's nothing you or the US shipper can do about it. Just be sure to use USPS and in the worst case scenario you'll pay GST+PST plus a $5 flat fee for customs clearance. Not much different from buying it locally.
