An RF-engineer from the USA was kind enough to provide me with a full set of boards for the Vector Network Analyser project. This way I don't have to send an order to ExpressPCB who otherwise offer an excellent service. The shipping costs to Europe is a is $67.00 for a 2-3 day courier, which is the only shipping option their software let me choose.
On a side note: with enough people for a group buy, you may as well order ROHS silver PCBs with silk screen and solder mask. The lack of solder mask can be a bit annoying at times.
