My original one was from Deepgroove, but they've stopped selling them.
It's had a lot of abuse on my digitizing machine, and still calibrates perfectly even after managing to bend the probe by running it into the bed...

Last two have been from imsrv - http://www.ebaystores.co.uk/imsrv/Pr...=p4634.c0.m322
However I have an adjustable one, which they don't appear to list any more.

Personally, I'd buy from whatever eBay seller has a probe with the features you'd like. As long as they're part of the eBay global shipping, all taxes are paid upfront, and it's tracked once it reaches the eBay shipping centre.


There are a few plans floating around for building touch probes, it's just I'd rather buy something that works, than spend days making one.
