Thanks for mentioning Omnifixo- when you said it's not cheap, I mentally prepared myself for a price tag of several hundred EUR. I find the ~60EUR price very reasonable (IIRC a single stickvise with PTFE jaws is around the same price point).
Well, I did mill the PTFE yaws for stickvise myself, and was seriously contemplating building a stickvise style vise (as I pretty much have the needed tools)- until I needed some Digikey part ASAP and had to fill the cart to free shipping threshold :)
