I, myself, really want a bumble bee. I was always worried a little about the wobble too, but people seem to get along fine with it.
And don't let the "holier than thou" types run you off or chastise you for owning/wanting one.
That snakes going to be born wether you like it or not, if you give it it's best possible life, then what harm are you doing. It's no different than owning and breeding an animal for its pretty color or what have you. If you can hold a wild animal captive and that doesn't bother your conscience, it shouldn't matter what is going on with the animal. If you get my drift.
