Surprising to see that I posted in here back in 2006.
Probably fairly shortly after that I got pretty into dubstep (before it became really popular and turned into crap). Back then most releases came out on vinyl only, so if you wanted to own some stuff buying vinyl (online and having it mailed overseas) was the only legit way of getting anything. Now most releases are digital, and many of the old releases have since been re-released digitally. I spent a significant amount of money on vinyl, and my collection really isn't all that big. I have about 60 dubstep releases and a handful of other stuff (Ratatat, Beastie Boys, DJ Shadow, Streetlight Manifesto, etc.), but many of the ones I have are actually considered classics and have gone up in value. Just as an example a copy of DMZ013 recently sold on ebay for over $25, while that's not a ton of money that is over double what I payed. That's $12.50 per song!
