You can use IceWM instead of TWM; it's almost as lightweight and much more stable.
Also, if any, CTWM (with the welcome screen disabled) can be as good as TWM but with better features (sticky menus and the like).
I don't like the look of IceWM but I will check out CTWM!
Edit: TWM is less cluttered and less features is actually more here...
