Paul is correct, if you buy a machine production or a machine from company that is no longer in business you are looking for trouble.
But if this is a machine of interest call Masterwood, and ask them about the controller, do they still have replacements or do they repair and the big question how much longer are they going to support this controller.
I can tell you as a repair tech on various routers, plasmas and water jets, it is the controllers that can be the death of a machine and a retrofit could cost you thousands of dollars.
Most of the other parts bearings, air components, ball screws can be found, items such as spindles, servo motor and drives can be repaired or replaced.
Just ran into a issue of a customer found a older machine great price, problems is we can't use a newer cad/cam program, its going to require a upgrade of 10500 for them to use.
Most of all have a inspection done, I repeat have a inspection done. I don't care who you are buying it from, have a physical inspection done and yes that means even from the big resellers. I have seen everything from brand new machines, machines with minor issues, to machines missing control boards.
SO....PAY FOR A INSPECTION...It will save you a world of hurt.
