Probing (not the Alien kind...) - advice?

Can anyone recommend a decent digitizing probe? I want to do some surface mapping and perimeter mapping of some fairly simple parts.

Initial research has let me to this probe:
And a wizard such as this: Probe-It! Mach3 Wizard – CraftyCNC (mostly to make it easy for perimeter probing of 2D parts) - I need to get the probe data in DXF.

I’m using Mach 3 and I have the Avid Plug and Play NEMA 34 controller with an open Aux port to connect the probe.
