I bought one of these about 20 years ago and have used it countless times ever since. Last week I finally buggered the allen key screws when trying to replace a broken bit on the drill end of things. Couldn't find it at Home Depot or Lowes and it was grossly overpriced at True Value. I panicked and went to trust Amazon and lo and behold there it was for $13 and change. Bought it and have started using it happily again. Wonderful device when you need to countersink and screw a lot on the same job. Got the original one to help Dad when he was building a wooden sailboat. Since then have used it for deck repairs, building docks, and many other things. It does what it's supposed to do with no headaches.
