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.

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?
