There are certain brands that normally just have no resale power and Dean unfortunately is one of them.
I was following a discussion about this on another board about fairly nice guitars and basses that people simply could not get a single CraigsList bite on at
any price, even in active markets, simply because of the brands. You can probably pick a few.
One wonders who buys these instruments the first time around.
I think it may be a regional thing, too. Out here you can't give away stuff from "pointy guitar" brands...even if they're not actually pointy. They're just stigmatized in too-Kool Kalifornia.
