I had basically decided that I was going to wait until both books came out, so I could compare them and see how much overlap there is, before buying either. With the prices in the $40 to $50 range for both books, that really discourages me from getting both. Sad thing is, if they'd both been in the $30 to $35 range that I've become accustomed to, I probably would have gotten both and not really thought much about it. And a year ago, I thought that was too much! I hope this price escalation doesn't continue...
