We have the same one. We wore out the main shaft after three years, but it has been used day in, day out to make eight loaves a week.
Electricity-wise, it is expensive so loaves work out around the same cost as shop-bought (depending on which flour is used and which options are picked) but we control what goes into the loaf and cut out the travel.
I tend to use the quick, three-hour cycle to keep the electricity consumption down, even if the bread isn't quite as good and needs more yeast. I never use the overnight/timer options for the same reason. I can get a good wholemeal/rye loaf done in three hours and a very good wholemeal/wholegrain.
I also make hand-made loaves several times a week. (We eat a lot of bread and bakes, almost all home-made.)
It would be nice to make all our loaves by hand, but that would take up a considerable amount of time and, what with working the croft full-time, looking after the boys, and blogging, the breadmaker does mean that I can infallibly guarantee one loaf a day even if interupted/distracted repeatedly!
The only way we could go to entirely hand-made bread would be if I was working the croft and the OH was doing the domestic goddess thing. That's not realistic in today's world - and I can't see her buying the domestic, cooking wifie thing anyway!
So, it's either the breadmaker or commercial bread. Easy choice for us.
