I used to sell the hell out of Bosch cordless tools. They're slightly higher cost, but you can drop them hundreds of times, or once from 40', and they'll still keep running. One of the demonstrations they'd do at trade shows would be to let people climb a ladder up to 10', drop the tool, and if it breaks and they can't get it running again, they win a free kit. They'd get between 150-500 drops between breaks. So they'd only give away 1-2 kits the whole show. Great tools, but you can't go wrong with the Makita kits. We used to repair a TON of DeWalt, so FYI, they're not always the most reliable. Stick to the Lithium Ion Batteries, because they're lighter and run better, very even power draw and last through hundreds and hundreds of charges. The old NiCd batteries are heavier and don't draw the same way.
