That depends on a lot of variables. You haven't given us much information. What's the over all condition of the machine, did you like the machine, is it part of a matched set, are you handy mechanically, do you like the orbital drive (short, fast stroke machines) or would you rather have the Pitman type transmission (older, long slow stroke machine), do you have time to rebuild a machine (big variable) or do you need something right away? These are only some of the variables. We can't give you a comprehensive answer to a wide open question like that and it sounds like you have some decisions to make before any questions can really be answered. In a nut shell, so to speak, we don't know your "life situation".
