IMHO, the learning curve is steep enough without throwing the uncertainties of an ebay razor into the picture. I think you'd do best to post a Want to Buy note in the classified section here for a shave ready razor. Generally, you will know that you are getting a properly honed blade that hasn't been screwed up by some ebay seller that doesn't know what they are doing.

Oh, the sweeney todd razor...forget it.
