I bought a $40 ukulele at a guitar place. A Hilo Model #2652, it gets out of tune if you don't play it constantly. A pos ;_; but its cheap. Go find one somewhere
I have a washburn Oscar Schmidt OU4 in a good shape with a bag that I'd be willing to part with for 60 -- I'm in the bay area (sf bay area, there are more bays I suppose). It has a very nice sound for the price.
