I've had success with a tool called inAudible, but that's been years ago now and I've no idea whether it still works. I do quite like https://libro.fm https://libro.fm as a DRM-free audiobook store. They provide zipfile downloads, and also profit-share with a lot of local bookstores if you have one you'd like to support.
