With the imminent death of the FaunaClassifieds Board of Inquiry I'm going to copy the reviews I've posted there over the years here and a few other places, so they'll still be available.
I purchased a pair of 2013 Tarahumara boas from Jeffrey Botticelli in AZ, KingSnake username Jeffrey, back in 2014. He shipped promptly after receiving payment and the boas arrived quickly, packaged properly, and in good health.
