redwhite,
I don't know if you've tried a 'Bird's Nest Fern' yet, but they have the reputation for being one of the easiest ferns (if not the easiest). They have thick leaves, which reduces their need for humidity. The thinner leaved ferns, such as a Maiden-hair, are best only grown in terrariums or somewhere where you can keep the humidity high on a consistent basis. Most houses don't have adequate humidity to keep those thinner leaved types happy.
