Just now reading this message--all the Pain Free editions are the same. One is a small size paperback, one is an over size paperback, and then the hard cover. But everything inside is the same in all editions, afaik. I have both the large and small paperbacks. So, get the cheapest of whichever size you prefer. Year doesn't matter.
