Stereo recording works pretty well i find with acoustic. I went and bought a pair of Behringer C-2's (ok maybe not the best brand but im a student, and they dont sound bad either!)

try recording the guitar as an XY pair. have both transducer heads close to each other and have them crossing each others path at 90degrees. point one mic at the sound hole and the other at the neck. maybe a foot away from the guitar.
