Also definitely look into ventless dryers - while not as quick as a vented one, the heat pump versions have come a long way from the classic condenser styles of the past.

Our ventless dryer is great. Maybe it takes 50% longer, but we're not running multiple loads a day so who cares? Smaller to medium sized electric ventless dryers are the most efficient dryers out there. (Of course we also just use clothes racks to dry stuff.)
