Best GPS to buy for Geocaching?

I'm looking for a good GPS to use for Geocaching. I was looking at the Magellan eXplorist GC, but that doesn't have a built in comp, which is a big downside. Are there any GPS devices that are Geocache friendly, and are accurate? I used the app for the iPhone, which was perfect, it located nearby caches, had the coordinates, and had a comp that led me straight to them, but I can't use an iPhone, I need a GPS. Help?
