The short answer is its a personal preference. Used guitars are fine as long as you have the knowledge required to determine if the used guitar is a bargain or anything less than a bargain. Used guitars can be a source of joy or disappointment for the unwary.
New guitars come with guarantees ensuring that the guitar is flawless in finish and construction for its respective price range.
