I felt nice, so I moved this to the proper section, rather than deleting it like I normally do.
I've used Brunton instruments and compasses quite extensively and with very good luck. My altimeter/barometer and declinometer are both older Brunton units. They have both gotten a little beat up over the years, but still function perfectly.
Looking at the prices and their warranty and based upon my experience with their equipment, I'd pick one up to try out.
