Looking for a book

I've been lurking for a while, reading the mystery locomotive posts with interest. Now I've got a queston.
Most of you will probably know of this book, but I saw it for the first time last weekend at a dealer at the Great Am. Train Show. Book is by Dorman, the title was something like "Chama/Cumbres with a little Chili". It looked like a really interesting book and I want to get a copy, but it was $135 and my parents weren't at the show. I was a little short on the cash but my parents now say go for it (they want it too). Any ideas where I can find a copy? I checked e-bay and Caboose Hobbies already, and there doesn't seem to be a website for Classic Trains & Hobbies, the dealer at the show.
Help appreciated!
P.S. got to operate a locomotive for the first time last weekend, a 15 Ton Brookville.
