I just got my lil girl and im fairly certain she is a 2010. She is TINY, 2 foot, so hses only like a few inches bigger than when she was born. so that alone tells me shes a 10'
Just look around on your local classifieds, check out pet stores, ect ect.
I cant really help you because I live in Canada, but I got mine from a newly opened reptile pet store.
Good luck
