What are DW 7000's worth?

I am thinking about upgrading my pedal but first I need to know how much I could get from my current pedal witch is a DW 7000 double pedal. The only think that is wrong with it is on the connector has just a little paint worn off. If I get a chance ill upload some pictures. Any guess of how much i could get for the pedal?

Thanks

What's so bad about the 7000 that you're already needing to upgrade?
