Besides posting it for sale to members here, if you're a member of Facebook, the FB 'Market Place' has been a good way for me to sell items locally. Unlike Craigslist, you can usually see who a potential buyer is which helps instill a bit of confidence of who you may be meeting up with. So far as eBay and Reverb, the fees, shipping costs, and sales taxes have pushed me away from those places.
Not an easy decision to sell gear sometimes and perhaps in the future you may find time to play with the keyboard more.
