Yup, I've replaced the Suunto with a Cammenga GI compass. The Cammenga looks really clunky compared to a modern baseplate compass and it's definitely not as user-friendly. However, if you don't mind the learning curve (and possibly the need to carry a separate protractor for any serious map work) it is a pretty good choice and very reliable in the field.

IMHO, an average hiker/outdoorsman is better off with a Scandinavian-style baseplate compass. It's just way easier to use and works well most of the time. The only real concern in my experience is mechanical reliability. Alas, even Silva and Suunto are no longer what they used to be. Build quality has gone down quite a bit and even the high-end (read expensive) models leave something to be desired in that regard. So the good old Cammenga is still a viable alternative despite its dated design.
