I just received my new tapper from an eBay purchase. It was about $100 delivered and has a #10-3/4" range. The fit/finish isn't great and we had to replace the set screws in the tap holders and drill and tap the threads to 10-24 from what ever bastard Metric size the were. But, I tapped twenty five 1/4-20 holes in 1/2" AL in just a few minutes. I used to tap with a handle that fit on a drill press quill and tightened the tap in the chuck. But that would only go to 1/2" and it was awkward. All said, I should have bought or built one of these 30 years ago! Highly recommended for any shop! I doubt I could build one with tap holders for $100.
