Not sure if you all have seen but GlobalGolf.com has a $25 try it before you buy it program on new clubs. For the $25, they ship you a free whatever and you get 14 days after you receive it to try it. Then return it and unless you damaged it, you're done. If you choose to buy the club, they deduct the $25 from the cost of the club and you keep it.
I was looking at upgrading my Ping G30 to a newer Ping driver and the used prices on the newest driver, the g400 Max aren't worth buying used. So I'm going to demo the new on just to see if it's that much better than what I have. The reviews say it's much more forgiving. But if I don't like it, I'm out $25 to get to try it for 2 weeks. Not bad.. but only available on new items, not used.
