John,
I would suggest you spend at least one day with Yoda. Included in the instruction is an explanation and some corrections/explanations of some of the befuddlements found in the book.
I have the 7th edition of the book. I think I would like to have an earlier edition at some point, but I am very interested to see what Daryl and Patrick (Innercityteacher)will come up with.
I also wonder just a little if there is an e-book version yet. That might tip me over the cliff to a Kindle or Nook.
