I have some proper straights, which I've used from time to time when someone has honed them for me, but never over a period of time.
I've used a super cheap shavette which cost me about 4 British pounds on ebay. Sanguine cool cut or something like that. Took a few weeks to learn but gave great shaves. Then a Parker SR1 for a similar period with the same results.
I've tried Feather SS non-folding and RG non folding. I kept the RG and sold the SS, but both great razors.
I've tried Kai Captain standard folding and Kai Captain Excelia folding, and love them both so have kept both.
I've also tried CJB non folding which is a Feather copy from Korea. Does a good job, but noticeably lower quality finish than Feather or Kai.
Feather, Kai, Dorco and I think CJB also make various blades for the Feather, Kai and CJB razors.
My personal favourites are the Kai razors and the RG Feather, but none of those are cheap models!
