I'd suggest Ibanez, Traben, Esp Ltd, Peavey as main brands to check out in that price range. For some the epiphone ebo bass would be good choice too. It and others by brands listed are gettable new thru internet stores for less then $350. Its going to come down to most playable best sounding to you out of those. Also check your local stores used dept, might find something really nice in your price range there that couldnt afford otherwise.
