I found my copy in a pawn shop. I had looked for it everywhere also, and I guess I got really lucky.
I'll keep my eyes open for another copy for you, but I've never seen another one (who knows, I might get lucky again!). In the meantime, I can send you a tape copy of my CD if you really want it. Send me an email with your mailing address and I'll ship a cassette copy to you.
p.s. I used to live in Biloxi.
