The one I have used is All About Monads:
   http://www.haskell.org/all_about_monads/html/index.html

Then, there is sigfpe's (always excellent) short but sweet blog posting:
  http://sigfpe.blogspot.com/2006/05/grok-haskell-monad-transformers.html

And finally (although I hesitate to mention it), there is my nroff-alike 
from Software Tools:
   http://www.crsr.net/Programming_Languages/SoftwareTools/ch7.html
(Note: I haven't gotten to it in the revisions following the comments I 
received here and there are many things that need work.  The notes are 
incoherent, it's more Pascallish than Haskell, and there are no 
guarantees that it won't ruin you forever.)
