I have a few Jordan's, nothing special as I destroyed them wearing them daily, but those I picked up over the years at a Nike Outlet on clearance, usually for under $100. Tougher to find them now.
The only pair I have that I keep in great condition (so far) are the Jordan V Retro Fire Red, which I got for my birthday (not sure how much my brother paid for them, but I know it was quite a bit as he had to search out a collector to find this specific model)
These ones are special to me, because back in 1990 it was my first pair of fancy shoes I got for basketball. Prior to that was playing in like $20 shoes. Couldn't believe at the time, that my Mom actually bought me $150 shoes. Felt like the luckiest kid in the world (and felt a bit guilty as I knew this wasn't really in our budget, and my parents worked hard to get me these)
