With the greatest of respect to the previous poster.

IMHO I would not go for CNC unless you plan to do lots of repeat production work. The programming can take far longer than one off custom jobs requires. On lathes it often requires carbide tooling to stop tip wear and inaccuracy, unless lazer monitering/ measuring is fitted and then you are talking large bucks. Most lower end CNC sizes from a given tip position and not actual cut dimensions. So you can get quite a difference if cutting hard steels (4140 , 416 etc)and HSS cutting tools.

Insted get a machine with Digital read outs (DRO) Once edge or centre is located, a push of the zero button makes life very pleasent.

I forgot to mention in the first post, always make sure the machine has pumped lube/cooling. Again high precision work is very difficult without.
