Google translate failed with all the frames, but it looks like you can get some motors that will work from there. I would avoid the electronics, as we have developed and accepted standards in Sanguinololu and RAMPS. Plus it looks like the controller boards they use are ARM based, while everything in the RepRap community is AVR based.
Summery:
NEMA 17 Bi-Polar Motors from there will be fine.
Controller/driver board is a crapshoot, with no support.
You can likely find the parts for the electronics locally, but you will have a hard time finding an assembled board. If you don't mind a short wait, I know that the guys in England have sources for everything we use.
