Counter top lemon trees currently coveting

I am very into these dwarf lemon trees. Don't they make these kitchens looks so bright and cheery? I'm in full-on garden purchasing mode, every impulse buy is being curbed right now. Perhaps in the fall, until them I'm going to sigh longingly at these mini-trees and pretend I can smell the lemons.

Do you have plants in your house? Any recommendations?
