Which lathes do the prices apply to??
Mr. Beach, you quoted prices of $200 for the Delta and $225 for the Jet. I am supposing these are the belt versions and not the variable speed versions. Both are good machines.
Most have suggested looking at the variable speed versions. Those prices will be higher. If I was looking at a new midi-lathe, I would probably look at the PSI Turncrafter VS for $230. It has the same specifications. The Delta and Jet VS versions will run quite a bit more. Personally, I don't mind changing the belt, but VS is a nice feature. The Grizzly 0657 at $325 seems also a good deal for a VS.
I would look at machines that have the standard measurements and accept the typical chucks, etc. (such as; #2 tapers and 1"x8tpi headstock thread).
Good luck.
