I really like the Friodur - she's a smooth shaver with no drama. I also like the squarish tang.

In that range, I'd go vintage no questions asked. You can get some very very nice blades,...

I'd get the Wacker. I already have one Friodur, and I am not a fan of TIs. Plus I've never tried a Wacker before.

(I wouldn't actually get any of them, but you limited the options....)
