Another thing I might do is go to the Razor forum, look at the 'razor clubs' sub forum. You might see some of those brands, plus you'll get a better idea of what kind of condition most guys look for. As gugi said, once honed those razors will shave (add another $20 to $30 to the price) but they are not in really great condition as they are.

I've seen some fairly nice stuff in our SRP classifieds recently for around $50 shipped and shave ready to boot. There was a Wester Bros Manganese Steel in there for $55 with bone scales and shave ready. I was really tempted but I have 3 or 4 already and the seller said it was for a new guy so I let someone else snag it. Keep an eye on the classifieds and you may do better.
