Rappers and hip hop artists love Mooncurser - records are the raw material of their art. Naughty by Nature once dropped 40 grand in one shot at Roger's - his biggest sale. It's your duty as a music lover, and recycling is ecologically sound. The actual object has more talismanic power than the reissue. I've always found that there's magic in those grooves, the weight of the disc, the smell of the jacket, the glint of the label.
Great vinyl is often less expensive than reissues or CDs.
And even if it wasn't - it would still be worth it. Of course there's the yard sale as well. But I believe the guys in the used record business, honest ones, and even the weasels, and there are a few, are a kind of treasure. And that little shop is just waiting for you, somewhere.
