Since getting a drum set is pretty expensive and cumbersome and whatnot, I've been thinking about getting a guitar. My favorite girl-with-a-guitar recommends the Martin DX-1. Everyone seems to like it, and it's less than $500 most places. What do you all think (especially those of you with geetars)? Can anyone recommend materials for teaching oneself guitar? I could take lessons, but with my schedule it's probably better I teach myself (at least to start). Please leave me comments!
