I guess it's hard to say what it is worth. We'll all find out in a week or so what THIS deck is worth RIGHT NOW.
I think I paid around $50 less than 3 years ago. I would personally suggest a "fair" price of around $75. I wouldn't be horribly surprised if it reached $100, but I personally wouldn't pay more than that. Of course, I'm no expert at all, so I could be high, low, or completely off base.
BTW, I asked kb2000 via PM to let us know if it was going to be put up for bid on ebay, I wanted everyone to at least know about it and have a chance to bid on it if they were interested.
