If you re read my post I actually said that the value of the original record isn't affected.
I don't know where you are from, but the whole ethos of the "Northern Scene" was built around the rarity of the music. The reason it has lasted so long is because one half of the scene has refused to accept the playing of anything other the original pressing at public events.
It doesn't matter how good the music is, familiarity breeds contempt, and the easy availability of even the rarest tracks on you tube, Cd and cheap re issues means that people no longer need to attend venues to hear the music. This wouldn't be so bad if there were any new discoveries to replace the classics, but there aren't.
These cheap re issues aren't being bought by people who want to listen to music they don't know. They are being bought so that they can be played at public events thereby undermining the Dj who has spent many years and many pounds acquiring the original.
Anyway, I no longer collect vinyl, but I still hate the re issue of rare records.
