Huh, I don't know much about monitors but I know that most are legal to sell. I have a buddy who's got at least 50 monitors of different sizes, shapes, and colors. Some of them are around 10+feet and eat whole chickens! They're extremely cool animals and while most are pretty docile when they're that big he loves bitey snappy animals and some of them are just NASTY. Still cool and he's got some extremely rare monitors. He's building a whole shed (it's more like a freaking house) in his backyard just for his big monitors it's gonna be cool!
