I guess it depends on what money your prepared to lose between cost price and sell price.
I have two snapped boards [had them fixed] sitting under the house that I'll never be able to move on but in the surf **** happens.
If you pay $1700 for a board and get around $1000 12 months or so later after plenty of use and hopefully enjoyment then thats not bad IMO considering the enviroment its been taken into.
If you buy something and hardly use it and then want to sell it maybe its more a case of bad choice[Iv'e done this myself way to many times

],
Cheers.
