All depends on what you are looking for but try searching for Myford, Boxford, Colchester, Harrison, Warco, Chester, these are just some of the lathe manufacturers.
If you can expand on what type/size of lathe you are looking for I am sure we can assist in refining your search terms.
Do you want a large (6" + swing) or small (<5"
lathe, gap bed or not.
What type of Mill are you looking for, bench top, Vertical turret, horizontal,Universal etc etc.
The more info you can give is better.
cheers
