I would say that is a very good unit for geocaching. Here are the geocaching.com user reviews for it:

Price is very good, handhelds are great for geocaching but not good for road routing (most don't do it at all). From the sound of the reviews, you won't have trouble loading geocaching information onto the unit. I think you've found a good one. I might pick one of these up, in fact, at some point.
