Yes, I was referring to current production, but there are a few early imports like the Jet 1024 that did offer a qc gear box. All are long out of production. The Grizzly "South Bend" Heavy 10 was another very expensive option, but also seems to have recently gone out of production.
The PM 1228 is the smallest lathe I know of with a qcgb that you can actually order, vs shopping the used market.
A South Bend 9A or Logan 9B-17 or 28-21 would be a big step up from the Enco / Grizzly / Jet etc, as that would give you a power cross feed and quick change gear box. If you were able to find one of the shorter bed models they can still be pretty compact, although they will be at least 100lbs heavier and the foot print is probably a foot deeper thanks to the motor hanging off the back side.
All are 50+ years old, so require a search and good looking over, but in my mind are some of the best options for a small lathe having a decent swing and all of the desirable features of a bigger lathe. Unfortunately the short 17" and 22" versions seem to be less common than the 28" and 34" versions.
Advantage to the 9x19/20s is availability. They are available new for about the same price as a decent used USA lathe, parts are available and tons of them have been sold since the 1980s so they are common on the used market. They also have an active support network of users who have figured out ways to work around some of the bigger faults.
