I've been looking at buying a threading jig and have only found the following that are currently available.
Chefware EZ Threading
Hope Easy Set
Baxter's Thread Master
The most robust and refined seems to be the Baxter's. However mounting to the lathe doesn't allow for transport to a different size lathe. I like the portability and different size thread capability of the Hope Easy Set but the manufacturer will not ship to the US and the US distributor shows it as being out of stock. The Chefware looks the most promising to me but doesn't include the different thread pitches as the Hope Easy Set. Unfortunately it also seems to be the most troublesome to use based on online reviews. Are there any other threading jigs out there that I've somehow missed? Any thoughts and opinions on what has best worked for you?
