After turning on numerous Powermatic 3520B lathes for a year I purchased a brand new Powermatic 3520c. Unfortunately it took four and a half months and four lathes to get one that worked. In my opinion the new C models are not built like the previous B models. I agree that Vicmarc, Oneway and Robust are all excellent lathes with great support should you need it.
If you have turning club nearby you might want to see if there are any members in your area that can show you or give you a hands on demo on any of the lathes mentioned.
