I've been trying to win a rear luggage rack on ebay for 2 years. I've seen them sell for more than retail but they usually finish out around $90. I guess I'm to stingy to pay retail for used parts, so I don't have a rear rack for my vulcan.
Speaking of things selling for more than retail, I watched a used factory tall sissybar sell for $250 last year. For those that are keeping track, that's $60 more than retail from the dealer.
Anyway, just sharing information
