I discussed this with Danny at D-Tek last week, and the shipping to Sweden is $100 with UPS (expedited) and $60 with USPS. I was going to order two heater cores which meant that shipping was more than half the cost. Not very worthwile.
I'm going to hassle some friends of mine into ordering some water cooling gear with me so we can share shipping, I suspect the initial shipping cost is the expensive part of shipping anyway.
