I am looking to buy a used machining center. Milltronics Partner 1's 1990-1993 go for about $12-14k. Cincinnati Sabre 750's ,same years, gofor $8-10K. The Cincinnati would seem to be a better machine - linear ways,almost twice the weight. Could anyone give me a pro and con comparison of the 2, with some idea of what may be needed in repair costs (mechanical items - spindle bearings, linear ways) as well as controller programming comparisons?
