Perhaps I should have annotated a bit; Price is not really important. I dont need the Ferrari of the tool set world, but $600 versus $4000, is not really important. I will be keeping these for many years, so an investment is fine. I will be using the tools during the Spring and then during the summer academic break to do major renovations, so some of them will see several weeks of almost constant daily use. DeWalt claims their 20 volt version (actually 18) batteries can be recharged in 30 min. Still investigating.
