Really, a great collection that only few people can have in one place. These things are all matter of desire. And the more desire you have the more you are willing to obtain them. Having 20 different editions of each album might be a cool thing and a sign we are real fans, on the other hand, to the outside world, it might be a sign of a psychological problem. I have received numerous looks and comments from friends, for a much smaller DS/MK collection. Anyway, each one of us has many other interests in life. And since my interests in music, books, movies and photography are equally great, I have to limit my desires and my collections. But I completely understand the collectors, since I am one and I am grateful he is so open minded to create these videos for the rest of us. Maybe we should create a database (EXCEL or something plus photos) , each one of us with the things we have, so that we know what is out there and compile a definitive catalog. I have made attempts but I am always falling behind.
