Industry Summit Black Boxes, any for sale, will pay $$$??

[panicpitsfunk1]

I would love to pick up some Industry Summit Black Boxes, if anybody has one, or some that they would sell. I do not care if they r from Upper Deck or Panini, I am interested in both, and I will pay good money for them, at least $250 per box, and I am willing to trade or negotiate with u. Please PM me with any details, or just post on this thread. Thanks for your time, hope to pick some up!
Thanks,
William
