I guess my only other question is my British colleagues keep saying, "Oh but they just eat electricity! Your electric bill will go up." How much of a difference could I expect? Frankly, to avoid hanging laundry everywhere on a permanent basis, I'd probably pay a fairly high price!
They're right. Tumble dryers tend to use a ton of electricity, quite a bit more than the washer does, for example. I can't give you numbers, though. Maybe a few hundred quid a year? I'll ask my husband later, but if I don't get back to this thread within a day or so, it's because he's still explaining it all in intricate detail.

(he's got his PhD in electrical engineering, and he's German, and this subject is one near and dear to his heart)
We have a 1-year-old, and I still manage without using a dryer, but I suspect as our family grows, I will at least want the option to be able to throw in a load of sheets, or whatever, when needed. Dishwasher is higher on my wishlist at the moment, though!
