I had spectacular failures because my dough (using my Kenwood Bread maker) would not rise, until another lady told me that the problem could be the yeast I was using, so gave me a bag of Hovis, which worked out well, and I ended up buying a big bag of Mauripan yeast from a baking shop, and the bread has definitely improved.
Carey, if you haven't gotten your bread maker yet and you like to bake, I would suggest getting a heavy duty Stand Mixer (most have dough hooks). I just got mine recently, and I was amazed at how easy it was to use. Of course it involves more clean-up, but I just felt that I had a little more control over the whole process. Whichever you decide I'm sure the aroma of fresh baked bread will be worth it.
