Ducks have ALWAYS been pricey, well at least since this forum was started, and for most of the time that at least I remember on the original Yahoo SRP forum. Guys were still talking about being able to find wonderedges for 30 bucks on ebay....but that must have been about the time they all started going through the roof (Lynn's video? :shrug: ) That said, I recently sold a Satinedge on the bay, and was shocked at how much it brought (almost the same number you mentioned above) because the last time I looked at 'Ducks, satinedges were 30 dollar razors, and DD Special No. 1's were 10 or 15... even then I would have rather kept the razor, as I know I'll likely never afford to replace it. They really ARE good razors.
All the talk of being patient, above....is true to a point, but vigilence is key. I don't think they are getting cheaper anytime soon. People used to think the same thing back on Yahoo...."I'll just wait until Wonderedges are 30 bux again"....still waiting, those guys....on the other hand, I've scored most of my 'ducks as parts of a "lot" in which it was thrown in and not mentioned with a group of other old razors...
