Christmas gift for my paw -in -law.

Ok I have been given the family job of picking the right "first" straight for him. I have $140 to work with and have found these 4 maybe 5 choices. He has expressed to me before of wanting a great "vintage" shaver. I would like to try to stick with NOS items unless someone has something that is in pristine condition and can guarrentee a very sharp edge. here are my choises are so far.

john at shaving shop

Cracked Ice otto busch

Boker

Classic Shaving

One of the first three on this page

All of these are German I believe so all will be good shavers. However, I am looking for the best value with the best shave and even the best resale.

Have at it guys, give me your opinions.
