This is a good one (I linked the thread about it), but it is out of print. You might be able to find a used one on Amazon. Quite a few of the shops in the book have closed, but a lot are still open. There is contact info listed with each shop, so can call to see if open (or Google the store). I take it with me when I travel in the 4 Corners.
Great Trading Post Guidebook
It also is a fun book to look through and learn from.
