What to buy for a 2nd lathe?

[Dr Stan]

If you really need/want precision I recommend staying away from the small cheap Chinese lathes as the old axiom "ya get whatca pay for" certainly applies. Look for a used small Logan, Harrison, Denford, Emco (not Enco), Myford and many many other brands that made good to very good industrial grade equipment. Of course you could go for my favorite, a Monarch 10EE. :)
