I got mine on ebay for $100 , one of the best hundred bucks I've spent. I tapped more than 150 2-56 holes before I broke my first tap and breaking it was 100% my fault , because I didnt have good support under the piece I was tapping and one end of the piece fell in the slot on the drill press table which broke the tap.
it will tap the threads in less time than it took to drill the hole
