Doc, DE blades are MUCH cheaper than Mach 3 blades. Ebay seller "howard1616" sells Turkish made blades called "Derby" for around 20 bucks per 100 blades. 20c per blade is quite a bit cheaper than 1.80+/blade for a M3. Derby razor blades give me the best, most comfortable shave, but everyone is different. Some like the Personnas you get at Walmart, some like the Personnas made in Israel, some like Feather blades, etc. Here is a review with pictures of Will's stuff from the Badger & Blade forums, if interested. How are they Vs Merkur?
