I bought a Milwaukee 6527 on Ebay. It was advertised as 9.5a with a tool-less blade change mechanism. It actually is 8a and requires an allen wrench to change blades. I don't care about the allen wrench, but I wonder how big a deal the difference in amperage is. I don't plan on building a house with it, so if I won't know the difference I won't make a federal case out of it.
(The bigger problem is that the shoe is missing, but I expect I can get him to pay me for a replacement. Fortunately I picked it up locally and paid by credit card (before being able to see it), so I have good leverage; the issue is whether I am owed anything for the amperage problem.)
