I have one of the older Harbor Freight minis. It is a rebranded Sieg. Sieg is in China and makes a lot of the mini lathes that carry all kinds of brand names. There are a lot of accessories and a lot of information available for them. This website has a ton of stuff for them:
https://littlemachineshop.com/Just keep in mind that you are basically buying it as a kit. You can use it as is, but you will get much more enjoyment out of it if you disassemble it, clean it up, deburr everything, and adjust the gibs. There is information on the website above showing you how to do all of that.
You also have to understand that you don't have the rigidity you need to take heavy cuts, and you will be limited in swing and travel. They are cheap lathes for a reason.
Having said all of that, I have finished out a couple of form 1 cans on mine, and find it useful for a whole lot of other things. I made enough money to pay for it several times over making specialty Pinewood Derby wheels for a while. I will have more space soon, and I might get a larger one, but I have definitely gotten my money's worth out of this one.
