Let me add my blue one to the mix:
I don't mind the stamp in the top and fortunately I was able to snag mine for the price of a ordinary small rivet Professional. The current price for the ones I see listed on ebay and elsewhere are double + what I paid for mine.
Mrs. PB gave me the green B-17 Special for Christmas for my Cannondale hybrid. I still need to mount it and take some pictures. Possibly later today.
