Although I don't like that I cannot buy the book at amazon, I can understand Monte. For such a small company as his, a book like this is a big financial risk. I suppose that most of the outrage comes from his stance on LGS, which I call bs on.
I just want to add one point that gets somewhat forgotten during the current discussion.
We have the amazon price of $75.59 for the Ptolus book, compared to the price of $119.99 plus shipping for the Ptolus book, the Night of Dissolution adventure and five copies of the Player's Guide. Then there's stuff like access to material on a special website and, what I personally don't care for, a signed and numbered book.
If you look closely, you will see that there is an effort to compensate for the price difference. You might not like it, and I'm not overly happy about it, either, but I can understand the reason behind it. I wouldn't want to gamble my family silver on such a project, either.
