We hate the drying function on our washer/dryer so much that we haven't used it since last year! We use the machine to wash them, then line dry (or dry on a rack inside if the weather acts up).
We're not bothered by line drying, though, especially since there are only two of us. It takes about the same time for the clothes to dry on the line/rack as it does for that machine to dry them!
Saves electricity, and the machine does the
washing part pretty well, at least.
It sucks that you might have to lose cupboard space to fit a separate dryer in there.
We have a similar amount of kitchen cupboards, judging from that photo, and I can't imagine trying to squeeze food for 4 more people into them!
