Alternative plugins for Twitme?

Can anyone suggest an alternative to using Twitme? When I first downloaded the plugin, it did exactly what I want. When I posted a blog entry, it sent out a tweet. But recent updated have crippled it for me. One update- still sent out tweets, but always showed me an error. Then the next update seemed to add a bunch of twitter functionality, but it is no longer working for me. It continually tells me there are 4 messages that are waiting to be sent. Even if I click the button to send them, the message doesn’t change. My twitter acct info is properly entered.

I don’t really need all the new stuff that this plugin has added. I just want a reliable way to alert my twitter followers when I have added a blog entry.
