I love how the point was brought up that it will raise the market for used boards too, which is true but I find it funny cuz alot of people on here would never recommend buying a used board in the first place!
There are a ton of good used boards and I'd recommend buying (being a cheap sob) if...you can find one available. 4 of 5 that I'm using this year are used higher ends. The problem is now finding good high-end boards that folks are getting rid of and that are still in good shape. 2-3 years ago folks were dumping them for the latest and greatest. There are tons of good condition beginner and intermediate boards that are good deals for newbs and the occasional rider.
