How fast you want it? Can you borrow one? I've heard some great playing on some really terrible banjos.
If you got dough and time your in business. The experiance is varied between these two things. Go to a good music store like Elderly Instruments in Lansing Mi. You could if you were flush and in a hurry just call them and tell them what style you want to play and they could maybe send you one on approval.(ask for Stan) I would trust them to get you started in the right direction no matter what your dollar or time frame might be.
