I just checked the member handbook for AGS and they do register Pygmy's so there is even more of a "wide" area to search!
The breed specific disqualifications for a pygmy are: Naturally Polled, Roman nose, cannon over 4.6" in bucks and 3.7" in does,Pendulous ears,and height..over 22 1/2" in does and 23 1/2 " in bucks.
If you check out the AGS site
http://www.americangoatsociety.com there is a list of district reps that you can contact for info. Hope this helps!!
