Your best bet is to go stainless steel, for a modern razor. But, they are pricey.
I prefer vintage razors anyway. When I first started DE shaving, I used a 23C. I found a Slim Adjustable and Fat Boy Gillette offered more pleasurable shaves, hands down.
+1. For modern razors the short story is "pot metal" (ok value for $) or stainless steel (expensive).
The other option is vintage, often brass.
