Well thinking of those requirments some good choices are:
Ball Python - I love my BP! But if you want a low care one you MUST buy from a reputable breeder or else you will have a world of trouble. Mine has been easy care since day one. Higher humidity requirments than corns, slightly higher hot spot as well.
Kingsnakes- California kings! They are beautiful. Low care. Sometimes more nippy than corns but quickly grow out of it.
Milksnakes- nippy, sectretive but can become quite calm as they mature.
