Based on this, I'd probably be inclined to say that a vintage razor wouldn't be good value for you. By the time you've sourced a mint one, or refurbished, you're potentially in to mid-top level artisan territory (having recently seen Carbon Shaving razors on Bests for £150). You're not going to get a better shave from a vintage razor, only the history which isn't worth the money if that's not what you're interested in.Aesthetic reasons are very important to me, I wouldn't shave with a razor that is in need of replating (OCD)...everytime I thought about a vintage razor, the ones in mint condition were too expensive.
I'm sure there are some great razors for some people but not for me.
Also, I'm not going to live another 100 years so I couldn't care less if in 100 years my SS razors are only good for paperweight
