I'm Young Choi from Univ of Southern Cal.
We're planning to buy a cheap used or refurbished PUMA 200/260 robot for our project. (Staubli TX series or Mitsubishi PA10 series and etc are okay)
It should work. or at least with small part change.
Anyone who knows information about it, please let me know.

Thanks!
Best
Young
