Ebay, and unfortunately, while they are certainly worth some decent money you probably won't get much more than $200 each for them unless you are real lucky.

Sell them both and buy an 08 waroo or other bow which will cover both wind ranges.. like maybe a 12M or 13M?

I sold my 06 15M yarga for $200 a year ago, and my 05 13M for $175 (or $150, cant remember).

My suggestion would be to set the buy it now price at around $200 and the starting bid at $125 or $150... (if you want a quick sale at $200). If you are willing to be patient to may get a little more.

Traditional C kites just don't seem to sell good these days. Good luck I hope you do better than that.
