-What should I look for before buying (what's a deal breaker)?
-I am not a wiz at fixing things, but could put in some time and effort to get it working. Once functional, I'd use it for a hobby, not for a job.
-How readily available are parts?
One end of the machine has a Darra-James model 640 planer.
My biggest use of the machine would be as a lathe. The other functions aren't as much of a priority.
