I use a chipper in my A bag. It is a Lynx chipper I picked up cheap at GolfTown a few years ago like this one (except in RH):

Just use a putting motion, and practice a bit to get the distance control down. Its not like you will suddenly put the ball 3 feet from the hole all the time, but you will definitely do it more often - and you will never scull it through the green and only rarely chunk it.
I don't use a chipper in my B bag, but I still use a putting motion when I chip. I simply do it with either an 8-iron or a 4 hybrid. I'm not as consistent as I am with the chipper, but still a lot better than the traditional chipping stroke.
