Most of the transactions that happen at the classifieds are non for profit; but, instead, to let the stuff someone does not need to go to a better home. Thus, if you don't like, or need what you have, just let others take better care of it, cover your original cost is fair, but push beyond it normally ends in no sale at all, as most GH's fellows are knowledgeable about keyboard stuff actual value. Some items are scarce though, but those are special cases, like clacks, or Special Edition sets; but for these, the community has an appreciation of the collector's status and its associated value.
