Ah - showing my ignorance again! If upgrading the electronics is worthwhile anyway, would adding a high speed spindle to the Denford be possible / sensible? I.e. would it be a good base to start, or for all of that hassle, is a new manual mill a better starting point? I've looked at some of the Proxxon's but read that these are far more capable for the money: Peatol Machine Tools - The Home of the Peatol Micro Lathe and Mill
