I haven't seen a tabletop dryer but my daughter had a Dri Buddi when she lived in a flat and loved it. Obviously not as fast as a tumble dryer but used little electricity and warmed the hallway where she kept it at the same time.
If the link doesn't work its the JML Dri Buddi Indoor Clothes Dryer Argos number 850/1147 and there are hundreds of reviews for it on the Argos site.
