If you decide to go with a spider, make sure you're able to deal with the possibility of it having a wobble that could require some assistance when feeding... My spider's wobble isn't nearly as bad as some of the ones i've seen, she only really shows it when shes eating and she looks like a doorstop wobbling all over the place trying to get the last bit of the mouse down. If you're able to deal with an animal that looks a little drunk sometimes and is all over the place. I vote spider.
