Hi Matt
I bought an E-trex H a few years ago as my first GPS, and am still using it today. All in all, as a basic entry level gps is does the job pretty well. It is very accurate, with a highly sensitive receiver, and is quite durable, as well as being decently waterproof. As far as I remember it was designed to be able to last about 30 minutes comletely submerged in water.
On the con side, the unit doesnt come with a pc cable, and after seeing that the cable's price was around R500 I decided it wouldnt be worth it. This means I have to manually enter all the waypoints using the hard rubber buttons, which is quite a mission if you have a whole lot to enter at once. I have tried the unit with the cheap eveready batteries, and they simply do not survive in cold weather, after about an hour the units dead. However with the more expensive longer lasting batteries, Ive been quite impressed with the battery life.
