I read it about 15 years ago and thought it was great! Find it cheap and enjoy...
I have a copy, I got it via ebay ( which I no longer use ). Back 10 or so years ago I picked up a ton of great Cramps stuff for very little money. Book's kinda cool, but wow, sure as shit aint $299.99 "buy it now" cool ? !

I don't really know the answers to your questions, but I have a friend that has an original copy of it (the edition that is worth some dough). There are several other books out there with very similar content, photos, etc. under different titles that sell for much less money.
So, if you are a serious collector, cough up the dough for a sweet book you'll enjoy. Otherwise, pay a fraction of the price for a new copy of a book with much the same info/photos in it and you'll still have a good time.
That's my two cents...
