Yeah, I made a post about this a week ago or something. I can't seem to find much beyond Ebay; if you keep a look out you may be able to nail a RB2 bundle for $50-$90. I'd really just do that, if I were you.
RB1 is even cheaper if you don't mind wired/no cymbal expansion room. I found a nice little Firefox Ebay plugin that helps you track your auctions, too.
Have patience, you'll get something. No cool deals that I know of, though.
