That sale may be reality, but proves some items that sell on ebay should not be used for value comparisons. Especially when you figure in the $110 shipping, which essentially raises the purchase price. Some may not see it that way, but whatever you have to pay to have it shipped is extra money you have tied up in that particular item. Parts values aside, as a whole its a $100 bike as it sits.
I changed my original comment to "an uneducated buyer" because they are probably a newbie with much to learn, and what I originally said sounded pretty harsh. Didn't intend it that way, but I hope they learn from this and start doing some research before buying another bike.
