I am thinking about moving to spray finish and have come across an old Fuji Super system for sale. I do not know the exact age but it has white text on it as opposed to the gold or yellow that seems to be more common. My question is, is it worth it to get a system that may be 10-20 years old for $100 or so? It seems in great condition with no overspray, dents, etc. My concern is the innards of the system, i.e. motor or any seals. Anybody have any thoughts? Should I go for it or run? Thanks so much.
