Those who want to have coins from 17 countries (random years), you can get those for €80 (nominal €72.5!) or 21 sets (includes the 4 mints from Germany) for €100. Shipping for those is €13 (Europe, US, mediterranean) or €22 (worldwide).
I also still have a set of oficial BU-sets, making a list and posting them later today I hope. Prices for those are of course more elevated ...
