Yeah, I just gave away a full set of Bosch 24 volt tools a couple of months ago. Batts with NiCad tech were $125 each for high capacity and I would end up with same issue again in x years.
I bought the Milwaukee 18 volt new technology tools and batteries. Also has brushless motors now.
Big thing that originally had me looking at those months ago was a post by Lumberjack about their 1/2 inch impact gun. Through the roof torque. (Be careful when buying, lots of diff models to weed through.)
