I paid 600 for one...but it was for my ex, and we wanted to get her a bike. It was a fantastic bike that she loved, so I think 500-550 is about right. I sold hers for 500 about two years later. The estimates above are very off IMO, even in a down market. Plenty of people know how nicely Lemonds ride, and 853 was great stuff. Anything under $550 is a solid buy IMO.
