When buying a bread machine I looked for one that all I had to do was to put all of the ingredients into at once and close the lid and press start and it does everything else until the bread is baked.
I personally like the simple no nonesense ones. THey are easy to understand and use. I have a panasonic. But they have a variety of types. You determine the types of bread you want to make and the kinds of things you want you machine to be able to do.
The things to look for in a bread machine are size, easy controls, ability to be disassembled and cleaned. the amount of power it uses some are more efficient. after that its just looks.
