I bought this Garmin Oregon 450 GPS unit in August for a college class. I have used it very lightly since then (maybe once or twice). This GPS hasn't been exposed to the outdoor elements, nor has it been dropped/mishandled in any way. The reason why I'm selling it is because I do not have a need for it anymore. The GPS comes with the original box, instruction manuals (various languages), a Carabiner clip, and a USB connector.
The best part about this GPS is the fact that it is geocache-friendly. If you're interested, please check the listing out on eBay. At the time of this posting, the highest bid was $285. The unit retails for $399. I'm shipping it worldwide, so what are you waiting for?
