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.
