Before you go out planning to get an Eastern Indigo, there are a few things you should know.
1. They are expensive. Babies run at least $400, usually more.
2. You can't own then in several states.
3. They are a high maintenance snake. They eat a lot, and crap a lot. And they really mess up a cage like few other species of snake. Most people who keep indigos have to keep them on paper and clean their cages almost every day.
4. They require large cages as they are big active snakes. Most keepers keep them in cages that are about 6 feet long x 3 feet wide (the size of a small bed). Where are you going to put that? Have you priced big cages like this?
5. You should only feed snakes prekilled food, therefore your indigo isn't going to "slam prey senseless". It will just pick it up off the cage floor and swallow it quickly.
There is no reason to feed an indigo live food. To do it simply for your own entertainment isn't really a great idea.
6. Breeding indigos is an artform. It isn't simply a matter of getting two and putting them in the same cage. Also, selling baby Eastern Indigos can be troublesome. You can't ship them across state lines without federal paperwork.
I'm not trying to discourage you, just to point out that these aren't the sort of snake one gets just because they are cool. They ARE cool, but there is a lot of work involved in getting/keeping/breeding indigos.
You might want to start out with one of the cheaper and easier to get morphs like a black-tailed cribo. You can buy imports of this species/subspecies for less than an indigo and can learn the intricacies of their care before jumping into the top end snake.
Check out some of the posts on the Indigo forum and learn a little more about these creatures. You may find it is just what you want, you may find it isn't.
