I called porter cable to buy a new battery for my drill, a 12V Magnaquench. $60 each. The guy said he had reconditioned Magnequech drills with two new batteries, charger, and case for $100, and that they were available in 3/8" keyless and 1/2" key chucks. Yes, 1/2" cordless. I got the 1/2" drill and when it came it looked and was packed like it was brand new. For $100 I ended up with (including my old drill, that just needed a battery) two drills, two chargers, two batteries, and two cases.
Very pleased. When I called to buy another for a gift I was told the military liked this drill more than the newer models and bought all Porter cable had for use on on aircraft carriers.
Porter Cable has a center in Houston that sells reconditioned tools and parts.
Black and Decker bought the Dewalt brand. When you buy DeWalt, you are buying Black and Decker shot with yellow plastic. It is an attempt to avoid the reputation B&D got from selling so many $9 drills. B&D makes three quality grades. Best - Industrial, Good - professional, Bad - consumer, designed for 20 hours of operation. Dewalt is the professional grade, suitable for contractors. Dewalt advertises a lot, but it does not make them the best.
Ya got me started. You wil like DeWalt, and reconditioned is good.
