Sell it for whatever you're offered, not going to be much demand for them. As I recall, they may not operate at a 1:1 ratio. Have you put it to use? Maybe that one time you need to drill into a stud wall to run electric, or something, you'll wish you had it. I have a 19.2 Volt Craftsman 3/8" cordless right-angle drill I use occasionally. I've seen a few of those over the years and I always passed on the opportunity to buy one. I've even seen one new in the box.
