From these links I think you can see that this is an expensive piece of hardware that is somewhat hard to find.
On average, the price for this particular model is approximately $700 (give or take a few bucks).
I'd appreciate serious bids only, but feel free to ask questions. If it is requested, I can take some picts of the box, switch, etc.
(Depending, I'd be willing to trade for some server gear [rackmount])
