South Bend is good. Hardinge may be even better, and they also now produce and service the Bridgeport mills, if you need parts. Many modern shops still keep a Hardinge Precision Toolroom lathe around (HLV or DV models). Hardinge's been around for over 100 years. Clausing, LeBlond and others are good.
There are lots of good brands, especially the older ones that might be more affordable. See
