The price for all parts is about 70€ without shipping costs. The PCB is 3€, in case you want to buy everything else yourself. Most parts are available from digikey. The gyroscopes can be bought from http://invensense.com or from a distributor near you. If you want a DIY-kit, I can send you everything needed to build it. Soldering experience is definitively required. The QFN chips (gyros and compass) are somewhat difficult to handle, but you can "reflow"-solder them in a pizza oven. I could assemble one for you, but this solution does not scale. It took me about 5 hours to finish the first one, and an additional hour to find and remove all the short circuits. :P If there is enough interest I'll try to find someone which builds and sells ready made modules.
