I've got a copy of Vin Russo's Complete Boa Constrictor that I no longer need (don't keep boas anymore). Here's the amazon link: http://www.amazon.com/Complete-Boa-C...ref=pd_sim_b_1

It looks like $48 plus shipping is as cheap as you can get it online. I'll sell my copy (only read once, still like new) for $40 shipped or trade for one of the more comprehensive BP books (like Kevin McCurley's, the Barkers', maybe even one of the DVD sets on BP care and breeding). Send me a private message if interested.
