Absolutely spot on Mark
If you take the idea to its extreme then you would only ever have to buy one top notch (replace this phrase with rare or exclusive or whatever) record, cos you could then have it cut, sell it on and use the proceeds to fund another. You could build a whole box of exclusives having only really lashed out for one.
I thought the whole point of this scene was to find and own rare tunes that suit what you personally like, for a DJ to have records that they want to play. I thought people who travel to hear certain DJ's do so because of the style and substance of their sets not just for one record.
I had a copy of Sam Williams which I foolishly sold, its not the rarest of records but its not that common, does this policy allow me to play my Grapevine copy?
Also, on a slightly different take, I have one of those "advance copy" white label pressings of Reconsider, who has the acetate? If this can't be determined then can I play my pressing cos its a great tune.
