I've sold a bunch on these to mining comanies, fireies, olice, ambos. They are exceptionally robust and will handle just about any knock you can give them. They don't cope with water that well although the literature will tell you they do. If you are going to get it very wet, there are better options out there.
A used one for a few hundred bucks is a great option for using in the field for non processor intensive stuff.
