If you MUST have originals, they can be hard to find and kind of spendy, but there are some great reissues out there. For example, I like to keep tabs on what Sundazed Records and Norton Records are putting out. Both have some great reissues. I just checked Sundazed.com and they have really nice pressings of a lot of the bands that have been mentioned including the Chocolate Watch Band, The Sonics, and others. They put out some killer compilations as well, if you're looking to sample some different bands.
I know it's only rock & roll, but I like it.
