Ideas for a new snake

[Trevor Flink]

So I recently purchased a female hog island boa and I plan on purchasing another snake next year. I was leaning towards a super dwarf reticle(don't know if they are legal in mass) I don't know the best place to buy one. I am also open to suggestions. There are a couple of parameters though. It has to be under $300, Average size for males is 7ft and under, it has to be docile, and it can't have hard care requirements. If you have any ideas just comment and please include a good place to buy them.
