If you don't need the capacity, you will be happier with a good mini or midi lathe. If you need the length, you can get a bed extension.
Do a Google search, you will get hits from discussions from various forums.
Some of the Sears are private label Palmgren lathes.
The paying search results are listed on the top in search engine. But if you search "Palmgren lathe problem", you can bypass the paid listings and go directly to the discussions about them.
When Amazon first carried the Palmgren lathe, the price was very attractive. Several people from a forum bought this lathe. They had a lot of problems, the initial service was very good. Replacement parts were sent promptly. Some had the head stock replaced 3 times. After some time, the service department was not responding and I saw the head of the service department's phone number was posted. I don't think it was a good sign.
Both lathes have Reeves Drives. They are high maintenance and don't run as smooth. It is an old technology and currently can only be found in lower end new models. Their existence is mainly for cost saving; I don't believe they use the best material to build them.
