after reading a posting on steel framed router with regards to a 3D probe
I was curious to see one working and found this rather good site but is there any better out there and who? makes them and sells them

I been on wildhorse innovations but $115.00 seams a bit steep ??

Has any one on this web site made one yet and how well dose it work ???
