Query: Wonderful book!

The whole series is wonderful, one of my absolute favorite manga series of all time. I know the books have been out of print for some time now, so I understand the high prices. I've been collecting the series via Amazon one volume at a time for the last three years because I only bought a few when it was out, I made the mistake of thinking it would always be around. I've paid anywhere from $7 for a volume, up to $40 and thought it worth every cent. However I must say that every last one of you on Amazon selling this for the prices you have listed are nothing short of a bunch of scavengers and vultures. I'm four volumes away, and this is one of them. I know that's my own misfortune, but really? $200?! TWO THOUSAND DOLLARS?! W.T.F.?!
