I got an almost new one for $70 shipped not too long ago, gave it to someone as a gift to go with their new iMac. Worth every penny, and she's in love with it. Money well spent at twice the price, considering how happy she is with it.
Edit: If that one on Amazon was sold by Amazon, and not a random seller, I likely would have bought that instead. But since I was buying from a random seller, I figured someone with significant ebay feedback was at least as trustworthy, so I saved the money, instead. That's a good price, though $50 more than I paid, shipped.
