Barry, we, that is my wife Emma and me, both bought second hand etrex Hs. They are simple to use, really accurate and great value.
If I may give you two pieces of advice, from our learning experience: buy pre-charged rechargeable batteries, in the long-term they will save you lots of dollars and secondly, get used to uploading and downloading waypoint and tracks onto Google Earth. It was this last part that really locked us in to this technology. Not only do we have a record of where we have been and when, but we can also share these paths and viewpoints with fellow outdoor enthusiasts.
If you would like to see where we have been PM me you email and I will send some over, along with some geo-referenced photos.
