I just scored a copy of Aitken's Taking the Path of Zen. WOW. Where has this book been all my life? He explains things with incredible lucidity to western students. The zazen instructions alone are worth the price of the book, which I got for 2 whole dollars. It's really like the companion book to The Mind of Clover, down to having matching covers. This is one I'll be carrying in my man-purse full time.
