Hi- When you get a chance you might want to consider the "Magellan eXplorist GC". It is made just for caching and is a wonderful little unit for the price and the enjoyment it offers. You can get one from REI.COM for about $150 USD and and has a very easy learning curve... almost turn on and go!
A nice feature is the "Find Closest Cache" which I like to use just after logging the recent find and I'm on my way for another hike!
Cheers- ChowRunner
