I just bought a set from Tony, and it was an overall great experience-- no negatives in the least.
I think that maintaining an availability of startups with vintage blades is a wonderful idea that can get a newbie into straights for a little less money, but it really is sort of a charity effort on the part of the participants. It's a lot more work to find the blades, dump the really bad ones, restore the OK ones, hone them up, and make them available at a low price. I would think it would be very much a labor of love, which doesn't really seem like it would be a good business decision for a commercial vendor. Much easier to buy dependable new razors wholesale, hone them, and sell them.
