You are a lucky man.
By the looks of the spine, that razor was already severely damaged.
It could have snapped at any time and caused a nasty accident.
Now your wife accidentally breaks it and wants to make it up to you.

In terms of razor quality, it won;t matter which you choose.
Livi, Le Grelot, TI, ... all reputable brands.

You may want to look around in the classifieds to see if there is something you really like. Several nice deals can be had there.
Good luck in your search.
