Welcome to SRP!
Rest assured that with your first razor you will roll the edge, cut your strop, nick yourself, and get razor burn. Accept it. Rolled edges can be honed, cut strops can be sanded, nicks can be sealed, and razor burn can be cooled. We've all been there and done that.

Whether you buy a new razor or a vintage razor the most important thing is that is professionally hand honed. A Dovo Best is a good introductory razor. A Ralf Aust is another brand in the same price range. If you decide to go vintage, then I'd suggest the classifieds on this site - the people here know what "shave ready" means.
