If you get an old British one then start with one with still functional solid bearings in the headstock and a main leadscrew nut which isn’t knackered.
Mine (pictures) had the heck beaten out of it but is great fun and still has good accuracy.
Modern cheap digital stuff makes 1-2 hundredths of a millimeter possible, eliminates lead nut measurement backlash issues and cycles between metric/imperial at the touch of a button.
I had to fix the backgear and the cross slide leadscrew nut myself.
After just over a year or so I can now also make up a new main leadscrew nut if needed, and even have a go at new headstock bearings.
They might not be perfect, but they’d definitely do the biz.
The most amazing thing about a lathe is that it can fix itself once you get past that initial clueless phase.
Those cheap digital verniers at a tenner a pop are manna from heaven for an amateur, so buy one as part of your tooling up phase.
