Racks aren't for everyone, some people like to display their snakes and watch them; racks can really limit the fun of observing them and just peaking in on them. I would say mix it up; there are a lot of pythons and boas that stay on the smaller side that you may really enjoy keeping, like: common boas, dumeril's boas, woma pythons, carpet pythons, blood pythons, and if you can handle the size...burmese pythons are all fantastic pets. For the money you can spend on Ball morphs, you could buy any of the ones I listed and have a nice diverse collection.
