I bought 3 off the Bay and paid no more than $13 for each one. However, each razor arrived damaged or broken (or sent the wrong razor). Others have noted the problems with broken springs which was one of the problems with mine. The Damaskeenes are old razors and it's not so easy to find a really sweet one. I lucked out and a very kind B&Ber PIF me a very nice Dam. One other issues with these razors is the handles are often spotted and corroded or rusted.
I would say pay a few bucks more to get a decent one. The prices spiked for awhile but seem to have dropped back now. So $20-$25 should get you a nice one.
