A brief article on our blog, "which GPS"
You state that the etrex 10 is a big improvement on the older etrex h. Could you be a bit more specific and say what they have changed?
I don't think I have had my etrex-h long enough to justify an upgrade, but would like to know what I'm missing :)
If all you need is a basic grid reference to tell you where you are in an emergency, then something like a second-hand Garmin Geko 201 will do just fine. As will one of the Etrex 'H' series ('H' for high-sensitivity, i.e. using a better GPS chipset).

More sensitive and efficient receivers, better user interface.
I upgraded from an eTrex H to an eTrex 20 last year. I find the maps useful - I use OpenStreetmap in the UK, which is free. You get GLONASS, which helps speed up the time to get a fix and gives better accuracy as the unit can usually see more satellites.
However, best of all is I get around 24h battery life on the 20. Can't remember exactly what I got on the H, but it was about 1 days walking. I leave the unit on all the time while walking, so I can download a trace of exactly where I have been. With the 20 I can easily get 2 days walking and usually 3 on one set of batteries.
