WP plugins other than Onlywire?

I've been searching for like a week for plugins other than onlywire that can auto submit your posts to social networks. Does anyone have any tips? I don't mind if they just submit to a single social networking service.

Onlywire is kind of annoying to use (for example, the program you need to install, only one fb page allowed, etc.)

I can't seem to find any plugins other than auto tweet.
Thanks in advance!
