Well whether Personna Med Prep and Gillette Silver Blue or any other well preforming DE blade is $16 or $36 for a hundred blades, the important thing to remember is that they are still a lot cheaper that 12 of the leading cartridge blades and IMHO, provide more bang for your buck regardless of the flavor of DE blade you prefer.
That's a good way of looking at it Dave. I hadn't thought about it that way, but now that I see it in a new light, I suppose even $50 for 100 blades is nothing compared to what I used to spend on carts.
