1. Gesshin Jinzo Aoto (synthetic aoto). Goes for $95 new. Basically brand new. This stone did not click with me. Its soft medium grit stone designed to leave a nice, finish on wide. $75 shipped. PP all included.
2. Aizu from Watanabe. 212x65x30. 1170g with base, 880g stone only (hardness HS32). Nice aizu with cool black dots. I'm still not good with natural stones, so this one is above my pay grade. $200 shipped (PPl etc included).
