Journal client recommendations?

I'm having some real trouble with my livejournal clients. I've got three on my Mac now, but not one of them has all the features I want. I'm looking for one that's got the following:

-An archive feature so that I can have private backups of my journal.
-Ability to post on several journal sites: livejournal, greatestjournal, and insane journal, without too much fuss.
-Ability to remember security settings (you'd think ijournal would be able to do this, but it cannot)

It would be nice to have the following:
-What you see is what you get text presentation.
-ability to look back at older entried and edit them


And it has to do all these things on a Mac. Anyone got recommendations?
