If you want a tame, friendly bird you can handle, make sure it was a handfed baby. They make excellent and charming, if demanding pets, but it sounds like you have the time for one.
If you don't have your heart set on a lovebird, budgies are wonderful pets, who can learn to talk quite easily. Some have extensive vocabularies and are cute and amusing.
