Is there an alternative to Adobe Digital Editions?

I am not willing to put any more hours into multiple factory resets of my kobo in an effort to get the stupid thing to work. But I also bought the kobo rather than a kindle in part because of its support of an open reading format. So--is there anything else I can use?

Have you looked at CALIBRE, a library control software that removes some of the format worries.
It is free at http://calibre-ebook.com/download and I find it excellent although the updates are a little too frequent for me, so I allow them to collect before doing so.
