Hard to find vinyl, obscure artists....

I just got turned on to a site, MusicStack.com, where you can find old, hard to come by vinyl albums (some with enhanced CDR's), you can find those really obscure artists that you can't find anywhere else (I've been looking for one specific album by a very old friend of mine who passed away for more than 15 years and I found it today!!!!!! Hooray!!!!). Then I got to searching around, thinking of bands from the past that you can never find anything from, and it was amazing!!! If you're into old vinyl (and new CD's from obscure artists), this is definitely the place you want to visit!! Can you tell that I'm really excited about it?? :D
