Look at the
G0602. It has a good reputation. I would get a larger lathe before the LMS variety.
Quality Machine Tools has a good reputation for service and customer support:

Don't buy a used one unless you consult someone who knows what to look for. A large number of old "good" lathes will be nothing more than a pile of headaches. I picked up a South Bend 10L and sometimes wish I hadn't since it needs about $1500 in work. That being said, when you find one in great condition that has been cared for, they will outlive you.
