At one time I had seven all together and it took about two and a half years of searching ebay. The ones with the Aluminum Akront rims are the nice ones, IMO. Come to think about it, the chromed ones are probably Akront too, but they are steel with plating..Contrary to a popular belief, they are not constructed of Fairy Farts and Unicorn Poop like some will tell you and thereby unobtainable.
