Does there exist a GPS Receiver that displays coordinates and nothing else?

All I want the GPS to display is my geographic coordinates; I need nothing else. I'd like to use it for geocaching. Ideally, it would have a basic digital-watch-like LCD screen that displays my coordinates and nothing else, but does this exist? I've searched eBay and other websites to no avail. I don't have nor want a cell phone, so please don't suggest phone GPSs.
