If you like the size and comfort of your 750, but don’t mind a price increase you should take a look at the Ewatec Gallileo Sol. It costs about $2K which a major downside, but the computer itself is pretty sweet. I was diving the 750 also until my transmitter went south on me around the end of the year. Since then I have been using my buddies Suunto Vytec, since it was free, and he had the extra computer after getting the Sol. I just don’t care for the hockey puck style of the suuntos and I like having hoseless.
