If a low-cost but high-quality computer is what you're looking for, you can't go wrong with this one. It doesn't have every fancy feature and isn't nitrox compatible, but if the basics are good enough for you (they sure are for me) then this is a real gem. I forgot my first one on a dive boat in St. Thomas one time (Lesson: be sure to look carefully around the boat before you depart!) and I didn't hesitate to go buy another one of the exact same model. My girlfriend is getting certified and I'm going to give her one of these computers for her birthday.
