well... you made out like a bandit. Thats an awesome price for an SD... I bought an MD250 for $300 about 6 months ago.
Can you send me a link to the auction? Im interested in seeing the lathe? Thanks
edit: btw. one of things thats a pain about prazi is the small user base, and difficulty in getting parts. At least that was the case with the smaller one i bought. There is a yahoo group for these lathes which may have some more info.
Also, you can get the plans from the US distributor, or from germany. If you need the contact info let me know and I will dig it out.
