Steve, just keep at your wife. I finally broke mine to the idea. LOL. She still hates that they are in the house but as Ozzy said, they do not smell and they are real easy to take care of. None of the die off of crix either. Plus, our waxies LOVE them. They practically maul each other when they see me coming with the forceps and deli cup. LOL
I went with B. latteralis. Needed something smaller than the lobsters. Plus, I was not big on a climber...
Ozzy, can't help you on the Tokay front. Try a local reptile expo though, sure you can find some there for dirt cheap. Might try dropping The Griffin a line too, he knows some weird freak woman who has tamed Tokays that she adopts out...
