The AL335 package is a good one if you are willing to spend that much. You get a good tooling package with it as well. It also has a wider choice of threads (4 to 60 tpi) than the AL320G.
One thing to check with the AL320G is that if the carriage feed and the treading all run off the lead screw, which is double the wear. The 335 has a separate lead screw and feed rod.
The site below shows a video of how his lathes have a key way to drive the carriage feed instead of using the treads of the lead screw. It also gives you a look over the machine.
