Mixed feelings here. I have got one (bought for me), and I use it occasionally, but really I feel I'm using it more because I have it and don't want it to lurk un-used than because I need it or it's that brilliant.
What I mean is, I make my own bread by hand. It takes 5-10 mins actual work to make, dead easy. The breadmaker bread is never ever as good as mine, isn't any quicker and only makes 1 loaf, whereas I make 4-5 at a time. So I'm left wondering what it is that the breadmaker is supposed to be doing for me.
As for using a breadmaker to make dough/rolls etc - why? The dough is so easy to make, literally 5-10 mins, and the oven always cooks it better anyway, so you might as well do the whole process by hand (or with a food processor if you have trouble kneading dough, for example if you have arthritis). O
I have used and/or had bread made in various breadmakers (including the much-vaunted) Panasonic, and while some of the loaves have indeed been acceptable and better than supermarket rubbish, they have never been as good as my bread. Even my breadmaker-loving relatives acknowledge that!
So to summarise, if you usually buy yucky bread then a breadmaker would possibly make better bread. If you want really good bread at little effort, make it by hand!
