I have seen way to many new guys do the "I am going to get an E-bay razor/antique store razor and fix it up routine" to even count...

Restoring a razor to even a shave ready condition, let alone mint condition, is an art... and the tools required to do it right cost $$$$$....

Take these guys advice, and start with a shave ready razor from the Classifieds from a reputable member here, and enjoy your first outing with a straight razor... Then decide which direction you want to take this hobby...
Just so you know RRD (razor restoration disorder) is one of the worst to catch
