Like anything you need to look at what is the need and then the "want".
The
needs would be something like -
Know your position
Mark a home point
As you know all GPS's do this or should!
I have an eTrx 10 as well for a spare if someone comes out with me and it does the job perfectly. Picked up of Gumtree for $90 brand spanking new used once. I do recommend these as they are light, take AA batteries, the AA can be rechargable and you can charge the unit via USB and also add way points via Basecamp.
They are super easy to use.
Cons - No references or visuals on the screen. You could be 1k away from a road and it will not show it, only the major highways.
The
wants are where the differences come into it.
As above I wanted something that gave me the ability to add maps and more data. I found a very good condition GPSMAP62 at Cash Converters and got that for $90 also "bargain"...
I loaded Shonky Maps onto it and now I have a fairly good base map with roads, POI etc... For a free map they are pretty good. I will update to a better TOPO but for the moment it is way better than the eTrex10 map so improved as well. It also has a larger screen. Otherwise very similar. Good viewing in Daylight and also takes AA batteries that can be recharged in the unit.

Cons - No extra storage for larger files, interface a bit clunky using buttons (touch Screen may be better)
You need to work out what your wants are and then tick off the list. The website listed below can give you a pick list to work with in the main search.
The new version of my GPSMAP62 is the GPSMAP64 -

The new eTrex are now Touch Screen (eTrex 25 up) with a larger screen as well and they look pretty good -

The eTrex 10 model is still the same -

Hope that helps a little in your decision.
