...just as an FYI, you can buy a standard BB tap set now that is made somewhere in Asia for pretty cheap. I don't know the quality, but Chinese tools have come a long way in my lifetime. They don't appear to have much in the way of taper, so probably just best used for cleanup (the most common use for these.)There's a Cyclus option from Europe that's in the $100 range, but the shipping will kill you. Most people don't need these. I use them sometimes, but I already have them.
