Hi Andrew, it's your money to spend as you will, but I would really recommend a cheaper razor to start with, for a few reasons, first you may decide straight razors aren't for you, in which case you can sell whatever you have bought and had the whole thing cost you too much, second you may damage the razor which won't be so distressing if it is a less costly blade and third you may decide the size and or grind aren't for you and you want something different.
Sorry if I jhst repeated myself from another thread, I can't remember if it was you I already said this to.
But all that being said I do appreciate your keenness for something that is quality and aesthetically pleasing to you, and your desire to not accumulate a whole load of equipment.
Bear in mind that you can usually resell razors if you try and don't like them, so it shouldn't be too costly to get a few and decide on what you like then get it scaled how you like. Or even get a full custom razor if you are so inclined.
