I would check for a (used) South Bend on something like CraigsList.
You find them often enough. If you check Ebay, everyone wants a ton of
money for them, or they buy one for next to nothing, and then take it apart
and sell the parts for ten times as much.
I got a working 9A for $400. It came with a milling attachment that I sold
for $300. (I'd never use it myself) and some collets that wouldn't fit. I sold
the collets for $75. So my net was $25 for a 1943 South Bend 9 inch lathe
with a four foot bed. It also has a taper attachment.
Of course, for that money, it probably needs something. Mine needed some
cleaning, a new back gear and spindle take-up nut (got both brand new on
ebay for total of $75, so I'm back up to $100 for a good lathe.
You'll see Atlas and Craftsmans on there all the time, too. They're pretty
similar. Don't be afraid of the old stuff. It was meant to outlast me, you
and all of our grandchildren..
