I have bought a couple of shave ready razors from the classifieds here, but I want to pick up a few more miscellaneous razors (especially when I start getting into honing).

If I go to Ebay, there are all kinds of vintage razors at varying prices. Most sellers seem to know nothing about razors.

Anyhow, what should someone look for when purchasing from Ebay or an antique store or whatever? Do you guys just have certain brands that you look for? There seems to be so many, I would think it would be hard to keep track of them all...

So... What should I be looking for?
