I consider myself to be a collector first (I'm just as happy with an image of a rare chip that I don't own as if I had the actual chip). I'm also a catalog author, which explains my penchant for images of chips I don't own. As a former new-issues service dealer (now retired) I was a seller for several years (although I do occassionally sell a few of my duplicates now and then). I've only sold two chips out of my personal collection.
And lastly, admittedly, I'm a "harvester junkie" ...
