Hey guys, at the moment I am still using my trusty Lowrance iFinder Go2. It has been a hell of good little handheld gps, but considering it was released in 2005, it is now starting to show it's age. I'd like to find something that is very similar in capability, but more modern with usb, a lot more internal memory than 64mb(micro SD?), and the ability to be updated. I've been out of the handheld GPS game for a while now and am wondering what is the best budget GPS for the hiker/camper/geocacher. I'd like detailed topo and roadmaps on my next model.
