Now the Jet, as Eric mentions is a whole different ball game in build and quality, and it comes at a price. How much the build/quality varies with any manufacture is to be seen, most can stand a little refining/deburring.
With the Graduate there's a lot of mostly long beds out there, you'd at best consider a short bed should you find one, if you get one, single or 3 phase, you'd likely need to allow for conversion to vari-speed, the kits are there if you shop round, and makes for a far better lathe.
You'll find the outboard is left hand thread so it's finding accessories or have faceplates/chucks cut with both threads.
Buying S/H you'll have dismantle/collection/handling/carriage etc, where a new buy would be delivered and if really good into your workshop, well garage and not the pavement drop.
