Honestly, it was a extremely difficult to find one of the PCI-Cards here in Europe. Nearly everything you find is PCIe. I live in Germany and the only shops I could find which sell those cards were from the US, but they wouldn't ship this item to Europe for some reason. (NewEgg, Tigerdirect and even Amazon.com)
Finally I came across a German Onlineshop which sells one of the Sparcle-cards for € 60, which is about $ 76. Crap! I believe, there is a very small market for PCI-cards here in EU.
