If you're getting one for lugs and such, you can buy the Ingersal Rand 3/8" titanium pneumatic gun. I got mine almost a year ago and I LOVE IT! I use it all the time especially for loosening lugs at work. 280 ft/lbs of reverse torque. I paid 300 for it back then. Also it won't use as much air as a 1/2" gun. I personally don't really like the electric guns as they're not as reliable, but you won't be using it everyday so you might benefit from it. I would recommend Ingersal Rand for any pneumatic equipment as they're the most reliable. I would stay away from any Snap-On air guns, they're absolute crap.
