I think all of my early Boredoms acquisitions were tape dubs of other people's stuff, and even then it was mostly from CDs. I had one friend who had a copy of Soul Discharge on Shimmy Disk (an excellent indie label, btw), but I never saw the original '89 Selfish LP in the wild. I'm happy that I didn't wait for vinyl releases before getting my hands on their Super Roots EPs. And even finding a number of their obscure releases in digital format (ah, the music blog days), I still have never managed to track down their cassette-only Boretronix collections.
I'm too much of a scavanger to be a purist.
