I have jaded opinions on "what it is worth". (and not sleds)
Professional apprasials, KBB, or your friends on JD, All have little to do with the better question,
What will someone pay?
Living in an area, with many potential purchasers may increase what will recieved for good (and services).
Items that have a local appeal are worth more. What is a worth more in San Fransico?, a snow shovel or a wok?
Has KBB considered that there is no ridable snow as of 1/1/13?
Look at the many homes "Under Water? Appraisers said it was worth $XX, 3 years ago, now it cannot be refi for $XX-40%.
How bad do you want to sell?
My sled is worth $2200, but if I want to sell in the next week, I will hope for $1500.
I have said little, I will just go back to staring at the grass stubble poking though the snow,
Best of Luck
