They actually don't come up for sale too often. It's not one that I've really been on the lookout for recently, but when I was big into getting every Griffey that I could, I didn't see it too often. I never owned one, but I remember them at one point being pretty expensive ($150-$200).
I saw that, but still more than I would want to pay. It's one of those cards I'll either stumble into my chance or probably never own. My wantlists are littered with cards that fall into the "it would be nice if I had this" category.
