Say what you want...in 10 years time I have yet to have my craftsmen screwguns fail to operate. I recently moved to lithium ion and added some impact drivers to the mix. What I found was that sears often have sales, plus they often will include both drill, driver and such packaged together. It was cheaper to by the package than a diver with extra battery. First time I heard the rattle of the impact driver I thought it was broke...though I love it for 3 inch screws
