I don't have a best sourde for Feathers because I have never bought any. The place you mentioned is one and ClassicShaving is another. I knowone of the SMF members also is a Feather blade source.

GA, there are a number of vendors who have them. I got mine from Robbins Instruments, where Gary got his. I've dug through the threads a couple of times to get the URL, so perhaps Gary has it handy.
Recently, someone verified with ASR that the lab blades are the same thing, with less rigorous sterilization and a much lower price. I bought the prep/for hospital use blades, myself, to be sure what I was getting. They are sharp and smooth.
I also still like the coated Treet Dura Sharps, which are also sharp and smooth, but the stainless Personna prep blades last a little longer than the carbon steel Treets (which cost considerably less).
