    Recommendations for low cost CNC probes?

    Just picked up a "new to me" Bridgeport TC22. I want to get a 3d probe for hole center finding, edge finding and some simple 2d scanning. I don't need extreme precision, but I'd like enough to accurately measure out dowel pin patterns (maybe within ~.001"). I'm hoping to spend <$300. It didn't seem like even a used Renishaw was within reach.

    I did some research and found about a dozen different units from $110 to $300 (and a few up closer to $1k.

    Centroid KP-3 $699 https://www.centroidcnc.com/centroid...uch_probe.html
    Hallmark Design ITTP $745 https://hallmarkdesign.co.nz/probe

    There is a lot of discussion on here about the wildhorse. Cost effective but based on testimonials I might want something a little better if possible. There is a thread on here on the drewtronics and that person liked it. Lots of discussion on the ITTP but I think it is a bit out of my price range.

    Anyone have experience with any of the other units on here?

    I'm running a drewtronics probe. I would say I'm about 90% happy with it. It is usually withing about .0005". I give it 90% because it will occasionally be off by about .003" My work around it to set up my WCS with the probe. Then I reprobe it and if it is within .001" (usually it is and way more accurate than .001") I know it did not have a random sticking issue.
