I had an old Hinari bread maker, and it was dirt cheap and made damned great bread. It would happily tolerate wrong amounts of ingredients, yet still make good bread overnight. So when it finally died a death, I swapped over to a Panasonic, and it worked, but was useless. It wouldn't make a good overnight loaf, and you had to be so careful over the amount of ingredients, so in the end, I learnt how to make sourdough bread by hand, and whilst I miss coming down to a fresh loaf. I get far better results.
What I have learnt over the years, is that you can use plain flour just as easily as strong Canadian and still get good results. You don't need to knead the flour to death (AKA Paul Hollywood style) and you can get away with just a quick mix and leave it in the fridge overnight, and then just shape it the next day. Pots of yeast don't go off till they are out of date (test by putting some in warm water with sugar), and soda bread can be knocked up in under an hour. And machines are great, but temperamental.
I am damned impressed with the perseverance you guys have shown, and if I ever get back to using the Panasonic, I'll now know how to fix it when it goes wrong.
