Don't forget:
695 - Mongoid http://github.com/durran/mongoid
seems to be the Rails/Mongo project to watch. They got a slick looking homepage too: http://mongoid.org
Hoping to try using it on my next project.

It's not quite as mature, but more documentation updates are currently in progress.
What didn't you like about MongoMapper and/or Mongoid? Starting from scratch is a big job.
MongoMapper in particular has come a long way since then but still has a few issues in my mind. For example, attributes are converted to/from their mongo representation every single time they are accessed, rather than only when the model is saved or loaded. I also believe MongoModel has a nicer model for typecasting property values (see http://gist.github.com/287379 for an example), and I disagree with the use of has_many associations for embedded collections.
MongoModel isn't perfect either, but it has been the path of least resistance for me in getting my app running on MongoDB.
