I'm loving the Z zeroer. Bolt the job down, move the cutter within 20mm of so from the top of the job, sit the pcb plate ontop and click go.
It moves the head down until it touches the plate. Then it zeros the z axis, adds on the thickness of the plate and then backs off 30mm.

You could use the same system for x and y but we use a round tube camera for x and y. http://cgi.ebay.com.au/5-0-Mega-Pixe...QQcmdZViewItem

Thats exactly what i setup today with help from everyone in the original thread, works great for $10 in materials! The camera definitely intrigues me though, i'll try to get that working next.
