Commie *******s! haha
Guys, there is nothing wrong w/ selling something for more than its worth. If someone is willing to pay a given price, then there is nothing wrong w/ selling a bike for that price. I mean seriously, this is America, it's a free market economy. I don't think my conversion was worth anywhere near what I sold it for, but a guy was willing to pay for the pretty colors.
IMO, the only thing that could be immoral in a bike transaction is if the seller lies about the bike. For example, selling a frame that has stripped out bottom bracket threads or is cracked would be wrong. Selling a perfectly good, nice bike for more than its worth is not a big deal.
Used car salesman are considered unethical b/c they sell cars that break down 5 miles from the lot. As long as my bike is in good working order, I can feel okay about selling it for a relatively high price.
