try Global Golf they also sell on EBay..

2nd Swing is on ebay or you can go to their website. I have bought a few of my clubs from them without issue.

There are a couple of big named retailers that also use ebay and are "authorized sellers". That only relates to new equipment that they are authorized to purchase for you from Titleist. Any second-hand, used clubs that they sell on ebay would not be under warranty or guaranteed for authenticity. They may do their best to take them in trade from a reliable source but that does not guarantee that the source got them directly from Titleist. If you are going to get a model as old as the 714, you will just have to take what you can find and hope for the best. Sorry Elson, probably not the answer you were looking for.

Be really careful Titleist irons are one of the biggest forgeries on eBay. And I bought a Newport select once and it was a fake. Luckily I got my money back.

But I think I might have a fake 710 ap2 8 or 9 iron.

Dallas Golf, 2nd Swing, 3 Balls, and Global Golf all stand by their used clubs. There are sites named like "iron finder" but I've not been impressed with the pricing and haven't had enough exposure on their warranty. There are several ebay retailers like Discount Dan's, Carl's Golfland, and Golf Galaxy that do little or no used club exchanges. Most of the retail stores that may carry used clubs don't keep a catalog of their wares, so it requires digging through piles of clubs looking for that needle.

2nd Swing today lists one 4I with a stiff flex shaft - and I think they will reshaft/regrip for a price. The other single 4 irons were all stiff flex DG.

Thank you, everyone, for all of the responses, @Don I see that one on 2nd swing, I might pick up that one and re shaft it my-self.

Global Golf is a authorized seller I had purchased a couple of clubs from them with no problem..
