Of the razors linked earlier, I'd probably go with the Ern rather than the Stiz. I own a Stiz and have never quite been happy with it, even after sending it out for pro honing. However I seem to remember Fergiebilly held them in fairly high regard, although noted that they take some time to hone.
I jumped straight in (see what I did there?) and ordered a 5/8 round point (Fritz Bracht Tennis from around 1940) from Billyji1. I also bought a paddle and hanging strop from him (both 3" width). The razor was recommended by Fergiebilly of this parish and it arrived from Billyji1 shave ready as described. Cost about £60.
For me, I don't think it matters whether you start on a paddle or hanging strop, as you'll cut up your first one a bit, but you have to get past that. My paddle strop is in perfect nick, my hanging strop has a couple of nicks in it, and once or twice I caught the folded over section at the end (bad for the blade). So my advice would be to get a hanging strop, but get one from Billyji1 or Boaby G (Rob Gallagher) for not too much money. Once you have got good enough at stropping to not make mistakes is the time to spend more than £40.
Straight shaving requires time (in the sense of minutes per shave, AND time to get proficient). It's not for everyone but it's rewarding in its own way if you like fettling blades etc. Best not to spend too much, but £100 gets you a good shave ready vintage straight from someone like Billyji1 as well as a strop.
