These are really hard to get, but I found this guy on the RepRap forums that milled parts in plastic. Looked good and he could probably deliver pretty fast i figured. Downside was he could not make all the parts, but the parts he could make were pretty big and time-consuming to print. Well, the parts are still not done over a month later and I'll probably try getting a refund instead.
So now I'll try to get them from ebay, where there seems to be sets for sale pretty regularly as of late. But they are not going to be cheap, good thing I stopped counting how much this will cost :p
