most are extremely hard to deal with when they are young, they take a lot of work to tame them. My boyfriend and I got one 2 almost 3 months ago, and my boyfriend is still working on taming him, I have nothing to do with him, cause he has hissed at me and tried to tail whip me and has bitten me, when I try to hold him he is not calm and will do a backing up thing in my hands then try to shoot forward, he is always alert try to figure out a way to escape or gauging the distance between my hands or my fingers and his mouth. and for a small lizard (at the moment, cause he is still very young) he packs a pretty good bite and doesn't let go willingly. My boyfriend can hold him and he is calm, but getting him out of his cage can be a task. You have to be willing to take the time to work with them, and give them baths everyday and work with them in the
bath cause that helps to tame them. For food costs, I would suggest frozen mice (only reason I suggest frozen is because it doesn't totally kick in their wild, aggressive, hunting side) we buy our frozen pinkie rats from the reptile expo when it comes once a month, we buy a months worth of food, which is about $15, if we were to buy it at the pet store it would be about $40-45 a month. I am not trying to discourage you, I just want you to know it takes a lot of work to tame them when they are young and you have to be ready for that and expect to get bitten probably more than once.
