I've been using StumpWM for several years now; it's great! There are some issues because the various desktop environments really don't want their in-house WMs replaced, and don't really document what needs to be done in order to just swap out the WM, leaving everything else. It's kinda sad really, and extremely anti-Unix. Still, StumpWM is so pleasant and easy to use that it's worth the minor pain of getting my desktop environment working with it each time I update machines. Highly recommended!
