What are the criteria you use to decide on buying or not? I saw a few at an antique shop, the one i was looking at was a Gillette Adjustable. They were asking 4 bucks for it. It looked like the handle had some gold coloring but the rest of the razor was silver, covered in soap scum, but it worked smoothly and the numbers 'clicked' firmly. I already have a Gillette SS, so this was just one of those times i felt like getting a different kind.
