Some manufacturers, such as Callaway, Tour Edge and Taylormade, have certified preowned options that are at great discount pricing. Most have seen very little use. If you know your specs you can find great deals. If you have never been fit and do not plan on getting fit, used equipment can be a great buy, saving a ton of $$$. I have bought wedges from Callway pre owned that arrived still in plastic at $40 - $50 less than new. I personally steer clear of Ebay simply because of the amount fake products. I would not buy a used top end putter from anyone that I did not know.
