I've had excellent results with Japanese sellers, including a NOS Dovo Bergischer Lowe, the old heavy grind version.

You do have to look closely, the NOS razors are old (the 'O" in NOS) and can have some age-related problems. Used ones yes, you do have to watch that toe wear, absolutely!

While there certainly is some junk put up, there are some deals too. I recently bought a fine Tanifuji BaBa Swedish steel with one spot of pitting near the spine for $47 and a low-wear Tanifuji Favorit for $36 with some fine pitting over much of it but the edge is stellar. Shipping will add some cost, but if you buy 2-3 of them the cost is quite reasonable.

Cheers, Steve
