If you want I can dig up my old source code where I converted a random number generator from a purely functional approach to a monadic approach, but I'm not sure reading it would help you, it's creating the code yourself that will be useful I guess.
Actually I stopped bothering long ago about 'understanding monads'. After reading many blog posts, wikis, tutorials, etc, often multiple times, I developped a fuzzy idea of what you can do using monads, and that's enough for me to use monads like IO, STM, State, Parsec, etc. without too much problems. I use haskell to solve many little problems in my job and I'm damned sad that I can't use it for larger projects. I feel I'm still a long way from identifying a situation where I would need to write my own monad, and be able to do it, but by the time such situation arises, I don't think it'd be too much a problem. That being said, I plead guilty of not provinding feeback where I found the doc lacking. I have no excuse.
