Japanese grammar primers

Recommended by 佐藤先生:

A Dictionary of Basic Japanese Grammar
A Dictionary of Intermediate Japanese Grammar
Both ed. by Seiichi Makino & Michio Tsutsui
Published by The Japan Times

Note: these books aren't cheap! I looked them up on Amazon.com and Abe.com, and they're each no less than about $40. Perhaps we can explore 佐藤先生's copies a bit before deciding whether these would be helpful enough to justify purchasing.
