Hi Vic
We were new to geocaching not so long ago, and after much deliberation purchased a Garmin e-trex. See link here for details. We also brought ours from these people and have been very happy.
You can find more details via this forum section too.
We've been really please with our e-trex, it does everything we need, and is under a £100. Now we have been geocaching for a while though we are considering looking for something a little more sophisticated, but that will depend on our budget! Hope that helps? Alan
