I use bread mix, too instead of mixing my own flours. Remember that it will come out denser than regular bread (not fluffy) and will be heavier and also a lot of times flops down (meaning it does not puff up like normal bread). The key is finding a good mix and you need to put it on 1/2 an hour less than the regular bread mix or something like that, you'll have to read the directions on the mix.

I use the mix as well and for what I can find in the store I love Pamela's.

My best friend said the Breads from Anna are really good. I haven't tried them but she has them up in her area. I know I tried the Bob Mill's pre-mixes and they just weren't what I expected. You may have to try a variety of different brands until you find a good one. If there's a frozen/fresh one you've bought that was ok, look at the ingredients and compare them to the mixes you find in the stores. I know I despise the ones that are heavy in beans. I usually look for rice flours and tapioca and potato. Those mixes turn out pretty good. Breadmaker's do work as I've made some good looking breads lately but I'm also hunting for the perfect recipe. I think it's mostly about taste.
