What to Use to Post to Twitter

So I made some changes to Twitpress so I’m testing them to see if they work. I’m not sure if I should use this or Twitterfeed.?? I would like it to be a shortened URL, so either use tinyURL or some other service would be helpful. What does everyone else use?

UPDATE: So I was just doing a search and found Twitter Tools from Alex King that looks to be promising! Guess I’ll have to play around with this idea for a little bit longer.?? Still curious to know what others use though.
