Nothing wrong with it. IF that's what you want to do. But I can't remember anytime that any of my friends excitedly came up to us to show their new USED clubs. Used clubs will probably need new grips sooner (an incidental but not necessarily cheap expense), they aren't custom fit so you play with what you get. As for resale, even the higher end clubs lose any meaningful value after 2 years. For example, I purchased a NEW 1 yr old '09 Tour Burner at a discount. 6 months later it was worth about $23 dollars. A year and a half before it was MSRP at over $250. So it was worth 10 percent of it's price in 18 months. Even at a garage sale, a few golfers always come around looking for clubs that are rare or on the cheap. they wouldn't even buy it for $10. I GAVE it to a friend who tried it, didn't like it and gave it back, so now it sits with the other misfit clubs. I've looked up my old set of Hogan "Ft. Worth" Irons on a few trade in sites- less than $75 for a trade. Hardly worth the postage to send them for a credit. As a matter of fact, I was JUST double checking that figure and it is now ZERO. The $75 number was for an ebay set I came across a few months ago.
Buying a "used" set, and then maybe having them adjusted, re-gripped and possibly lie adjusted or whatever- might as well buy a new set for what you're going to spend.
As I said- in MY case, a set of decent "clones" was the way to go.
