Well I'd like to think fellow boardies will try and help each other out.
Whereas on Ebay, everyone is trying to get top dollar for everything.
I like to stick to my motto of "Something's only worth as much as someone's willing to pay for it."
I sold my Mint and complete DX02 for $240 shipped, yeah I'd like to have gotten more, but I helped out a fellow boardie by letting him go at that price.
However I personally don't think that a incomplete(missing a few hands is ok or a few batarangs or bombs) missing the backpack or sonar head DX02 should go for any more than $150. The Sonar Head and Backpack(and sticky bomb gun) are what set the DX02 apart from the DX12. They're just too detrimental of accessories to be missing.
