I have a Makita DA391DW, 9.6v. 3 years old and still runs beautifully, like all my Makita stuff, and it gets used nearly every day. In fact since I dropped my old 6228 and smashed the trigger, it's my only cordless drill presenly running. Sometimes I wish it had a 1/2" chuck, but it's horses for courses. If you already run a 12v Makita standard cordless pistol drill, the DA312DWA might be better- you would then have interchangeable 12v batteries. Recommended.
