Well I got the Mikita mini impact gun. I decided not to get the kit with the drill because i would never use the drill/driver.
The little impact rocks! I got it because it fits in my veto bag and i only use the impact for taking off panels and driving screws, fits the bill perfectly. The battery lasted about 2 days, not too bad since it came with 2 and they charge very fast. IM glad i dont have to carry around my 18v impact anymore.
