The price is the reason I stayed away from AAS initially, but then I got my hands on it at a curriculum "petting zoo", and decided it wasn't for me anyway.
I haven't seen AAR. Well... that's not true. I have. It was at a HS conference I went to, but at the time, I didn't pay much attention, because I'd already looked at AAS and saw the price.
Sorry... that wasn't very helpful, was it?
Perhaps this will be more helpful?
