Dave Bock posted this list of what we affectionately refer to as the Fab Four:

All four textbooks were developed specifically for AP Stat. I think it's a mixed lot on the list on who uses which textbook. My textbook adopted the YMS book, but I went with POD this year and have been immensely happy with the book. If you have the time, contact the textbook reps for each publisher and have them send you a copy for review. It's worth your time.
