WALRUSCP $15-20 is pretty much the price point for higher end Twitter clients (e.g., Twitterific is $15). I bought Tweetie while it was on sale early on, and I have to say I like it for its simplicity and clean interface. I also love Eventbox, and pull that out when I am doing heavy lifting social networking (Google Reader, Twitter, Facebook, etc., etc.). Atebits should probably consider pricing Tweetie at $13-15 to directly compete with Twitterific. I think they'd find a lot of success in doing so.
