As Craig points out, Vise-Grips is the easiest and quickest solution. If you get desperate - and I don't think you are there yet - you can buy a set of left-handed drill bits. Chuck one into your drill, set the drill to "reverse", and begin to drill the hole. Quite often, the reverse torque on the screw will break it loose and back it out. If it doesn't, you can also buy screw extractors. These are like tapered left-hand drills. You push one into a pre-drilled hole, and turn it in the backward direction using a wrench. It will feed into the hole until the taper exceeds the hole diameter, then it will jam. Continue to turn it, and it will grip the screw and back it out.
You can get both left hand drills and screw extractors from Harbor Freight for a surprisingly small cost.
