I am about to celebrate 65 years on earth and it may require a new lathe. I read a lot on various forums from the loyal following of PM 3520B, mustard monsters. They are in the $4K range, however there is another plateau at $6-7K with Robust, Stubby, Serious, Oneway….. lathes. All are within the consideration of this aging relic. Anyone have suggestions or opinions on their pros and cons? Which is best and why? I would be upgrading from a 16”, 2 HPGeneral.
