I've never owned a regular clothes dryer; I've always dried my clothes on a line in the summer and on drying racks in winter; it works well enough for me (sheets are harder to dry in winter, though) and has saved me many hundreds of dollars in electricity costs over the years.
There wasn't a good place in the yard of our new home to put in a regular clothesline, so I decided to get a good umbrella-style dryer. The one I found is called the Lady Plus, it's made in Switzerland by Stewi, and I love it. What's especially nice is that when you're not using it, it folds right up just like an umbrella:
When it's pulled open, it can hold at least two full loads of laundry, including sheets. It rotates, so you can stand in one place and spin it around to fill up the lines (and when the breeze blows it spins as well)
This thing wasn't cheap ($250 Canadian), but that's still cheaper than a new energy-efficient electric dryer, and there are no electricity costs. The only pain was that I had to dig and pour a concrete footing for it, but that took about 20 minutes. I'm happy!
