I think you may have some model and manufacturer info mixed up. 46-719 although not valid is closest to Delta 46-715 (14" swing, 3/4 HP, reeves drive) full size lathe. Shop Fox seems to have a mini that is a clone of the Jet 1014. Shop Fox W1704 (http://www.factorynew.com/BrandFeatu...and=SHOP%20FOX
I'm not sure what you're interested in turning, but here's a link to a comparison chart for different lathes put together by the AAW (American Association of Woodturners) http://www.woodturner.org/resources/LatheSpecs.pdf
Depending on what you want to do, the lathe specs should give you a solid idea of what you might want to get. You may also want to join a nearby turning club, you can locate one at http://www.woodturner.org/community/chapters/
All that aside, I would steer clear of the Delta line, but Jet & Powermatic have great lines that take the abuse lathes are put through.
