I'd check the first one out very carefully before buying. There appears to be a fair amount of surface rust on it. Not a huge deal, but it does take time to deal with it.
It looks to me that there's a significant ridge near the top outside of the near way close to the chuck. The ways are oiled from the apron, and when the oiler quits, worn ways result. These have hardened ways so are not so easy to fix.
The Bay area lathe has a D1-6 series Camlock spindle while the Chula Vista machine has an A5. To mount a chuck on an A5 spindle, the backplate is bolted to the spindle thru its face, then the chuck is bolted to the backplate. It also has about a 1-7/16" spindle through hole. The D1-6 chuck comes off as a unit and has a through hole greater than 1-1/2". The A5 system works perfectly well, but is a pita if it's your only lathe and you're switching chucks/faceplates, etc.
The Chula Vista machine is missing the longitudinal rod that holds the adjustable stops to kick out the carriage feed. The Bay area machine is 10-15 years newer, is a gap bed lathe, has a longer bed, a QC toolpost and a collet closer. It's a lot more lathe for about the same money.
I live in lathe-rich New England, so am prob underestimating West Coast prices, but I think the Bay area lathe is priced well and the rusty lathe is overpriced by a factor of at least 2.
Fabworks has it right....
