Check out MetroTwit ( http://www.metrotwit.com/ ). I stumbled across it about two months ago and I've been using it ever since. It is a bit pricey for premium, but I bought it anyways (before it looked like Twitter was killing API access).
Unfortunately it's Windows only which doesn't fix the issue of Twitter for Mac being put out to pasture. It is a great twitter app if you ever use Windows though
I'll give it a shot, thanks for the suggestion! :)
