If you get them fairly young and you spend some serious time with them, they end up not being that bad. I've posted before that when I first got my colombian (Blake) he was pretty bad. I'd spend 45 min. a day just slowly getting him out of his cage. Even now I handle him every day. But he's totally a puppy dog now. Gets a little grumpy when he's rudely awoken, but then again so do I.:P It just depends on how much time you are willing to devote to "taming" the lizard.
