For my starter gun, I bought a JBL 42 woody used at a pawnshop. The gun was in perfect condition, and needed nothing. I paid $75, new it's $200. Check carefully the straightness of the spear shaft, the presence or absence of a tip, and the condition of the bands. Make sure the spear groove is clean and clear with no chipping or fraying of the wood. Make sure the plastic bits are not broken. load the spear shaft in the gun and listen for the trigger mechanism to click. without loading the bands, pull the trigger and listen for the click again, and for a clean release of the spear. If bands, shaft, or tip are unacceptable, that isn't a showstopper, they can all be replaced, but it gives you a negotiating point. A 42" gun will be fine for snapper, small grouper, hogfish, and what else would you want to shoot anyway. You won't need to move up to a 55" freeshaft euro for a number of years anyway, unless you turn out to be a prodigy.
