So, i got the printed parts from http://3d.reinderink.nl/, the rest from 3d printing for you. I started building and have finished the frame.
At the moment i'm stuck on the y-carriage, and desperately trying to find more information:
the http://garyhodgson.com/reprap/prusa-mendel-visual-instructions/ are not updated for the prusa 2 and there seem to be big differences at this moment:
in the prusa 1 the pla bushins were placed on the smooth bars and then the bottom plate was glued on it.
now the order seems to be to first place the printed clamps on the thick sheet with bolts, add the lm8uu's and then place it on the rods, however i can't find the precise locations for these bolts.
http://reprap.org/wiki/Thick_Sheet says i don't need a separate bottom and top plate, however on other locations it still mentions them both.
i think i'll try with these instructions, and let you know if it worked.
