I use a Tyme Avon and a Poolewood as a full time turner. Both are strong, reliable lathes that will do pretty much anything you ask of them. If you want an all singing, all dancing, fully automatic electronic variable speed lathe to start with then start looking for things with four digits after the pound sign but to be honest, as a beginner, look out for Tyme (there is a cub as well tyhat is smaller), Poolewood, Record, in the 2nd hand places. Good, solid and reliable. record tend to be a bit limited and have the 1 morse taper and the Avon and Poolewood will need adaptors for the chucks but aside from that they will do pretty much anything you ask from pens to large sized pieces.
