you can sometimes find good deal on a cam machine
the one I was looking at was a bare Tornos M7 no turret or attachments
they were giving it away because they couldnt find anyone
who knew how to set it up anymore and not having a turret limits
the jobs that it could run to plain shaft work

I agree
a hand machine would make great base for a CNC conversion
even stripping it down to the bed and spindle would give you a
better base to start from than the small import lathes
