Well cheaper maybe (even thought in France these are expensive and hard to come by the last one I saw went for over 3500€) but having worked on some "old" grinders I know that getting one is something of an act of faith because wear is sometimes so high that a rebuild is needed and that's something I do not feel like attempting.
But the bigger issue is that the parts I need to grind are over the working envelope of a machine like an MG12
