There was a recent 30th anniversary vinyl edition of DSotM that I picked up a while back. Remastered, with all the original stickers and posters and stuff. I'd say it's worth the price tag (which was around $25-$30 when I got it).

I never realized just how much of a difference in sound quality there was between analog and digital until I did a test myself with the CD and vinyl version of "Communication Breakdown" by Led Zeppelin (I've got all but two of their albums on vinyl). The vinyl sounded SO much better. The drums had some serious kick to them.
