Any value still in the old Dr. Christopher book?

I'm so glad I found this forum...
I'm with you guys as far as Christopher/Schulze being the way to go.

I stumbled across a link to get Schulze's updated "20 Powerful Steps..." book for free, but alas, it is no longer available for free. You can't even order it online, but his company does still sell it for $10. It's in his catalog (which you can at least view online).

I ordered 3 copies: 1 for me and two for my kids. They even gave me one of the copies for free (I'm assuming because I was a first-time customer, but I didn't ask). I wanted to get the xtra copies before it goes out of print, and then all that will be available will be the heartless Amazon opportunists selling theirs for a small fortune.

Side note: I'm sure most know this, but thought I'd mention it. I've been buying books online for a long time (mostly technical books), and Amazon has put out of business most of the other vendors I dealt with. There are 3 places I look now: Amazon, half.com and ebay. half.com might be overlooked by some, but if you are looking for used, check it out. They are now owned by ebay, but it's still a separate site (the seller's rating is their ebay rating). Some people/resellers put their books on both Amazon and half. I have seen them list the same book with two different prices!

Anyway, my question:
I know that Dr. Schulze is "the man" now, but does Dr. Christopher's School of Natural Healing book still have any value?

Your thoughts are appreciated.
