Dependent on the rareity and condition of the tunes, I would say that generally you are better off ebaying individually. Alternatively there's the site on Soulsource or "the hassle free record selling group" on Facebook,https://www.facebook.com/groups/hasslefree/?fref=ts If you have some high quality rare UK items, its worth considering John Manship to auction them off individually. Here i'm thinking near mint or ex+ copies of tracks like The Invitations, Incredibles or scarce TMG's. Harsh though it might sound I feelthat most guys with their original "in the loft" collection have an inflated idea of their value. Condition is everything and selling can be hard work. I will be interested to hear what others suggest.
