This guy makes good products (e.g., he also makes Dark Adapted). And he supports them. Several years ago, when the economy was better, he custom-made a piece of software for me at an exceptionally good price. And he still supports it when he can. (In this economy, he has to focus on his bread-and-butter software; and I don't blame him.)
UTC Global Clock has been wonderful for me. My wife is currently in France for several months, and it's really nice to be able to have a simple time for over there in the upper right corner of my screen. It's unobtrusive, and it's highly customizable.
