Damn man, do you really want to spend 600 bucks on a snake at your age. Most dogs don't cost that much. I know some older owners spend that much on snakes as pets but they have money to do that.
Personally once I turned 16 I was NEVER home. I put all my money into my car at that age (and still do haha). I would think at your age to just stick with a less expensive morph and build a rack yourself. Put some money toward a car. Trust me once you get freedom your gonna love it.
Just some stuff you might want to think about.
