Haven’t checked the price of the one on offer and I’m sure you would get it sold on if need be, possibly at a loss. It’s by far the best looking GEM razor. That aside, in an ideal world you would try a much cheaper vintage first to verify that you like how these shave. Unless being economical is thrown overboard and you’re on an unlimited budget, obviously.
I never quite got along with the two vintage ones I tried but nevertheless pulled the trigger on a Sabre Level 2. It’s not the one I reach for most, but I believe I could dramatically improve the shaves it gives if I gave it sufficient time. In other words, not the smoothest nor the closest shaver for me currently.
