Having a dryer in addition to your washing machine is a good thing. It allows you to quickly dry your clothes, without having them outside, risking a rainfall, or neighbours wetting them. You do not want to have your precious clothes getting soiled like that.
So I strongly recommend you getting a washing machine with a dryer. One model of Washer Dryer that I recommend is this good one from Electrolux.
