Trade in of aTechnics turntable.

Those of you who have traded in your old Technics table, where have you found to be  the best places 
to contact. I am considering trading in my Technics SL 1200 Mk 5 on an upgrade.
Your comments are greatly appreciated.
If you're asking how to get the most money, take a lot of really good pictures, describe the table in detail, and post it on eBay no-reserve auction.
