Brain Bag trade?

Anyone out there with a black Brain Bag willing to trade for a sapphire (blue) Brain Bag? Mine is in like-new condition, was originally sent to me as a review item, and hasn’t been used in more than two years (mostly because I’ve been using other bags for review purposes).
I love the Brain Bag, but would like one in basic black, and cannot afford to buy a new one. If you’re interested in a trade, please e-mail me, and hopefully you’re savvy enough to know what to do with that e-mail address.
