Old School DRO.  Use a dial indicator.  Its the default for longitudinal 
(Z axis) lathe work.  Lots of people will set a zero to work towards on 
the indicator.  I think its easier to hit the mark than a digital DRO 
because you can have it in your field of view while watching the work as 
opposed to having to look up at the DRO.
