I am not an expert at machining. I purchased the Harbor Freight 7 X 10 a couple of years ago on sale for around $300 at that time.
After a lot of cleaning up and adjustment I find it very suitable for the small precision work that I do as a hobbyist. Being able to reproduce small parts with accuracy down to better than .0005 with no problem.
Thee are a lot of good web sites out there that provide a lot of information on adjusting and setting up the Mini Lathe. Those were very helpful to me, at the time, in getting my little lathe as tight and smooth operating as possible.
I would not hesitate to purchase another one, knowing what I know now.
