The countryside around me is interesting but very confusing - a mixture of country roads, farm tracks, bike tracks, canal tracks, patches of forest. It's both a temptation and a navigational nightmare, and I have no sense of direction, so I want a GPS that will let me retrace my path home.

- Do the cheap Garmins work well for this? I was thinking of an Etrex H

- Is the Etrex H's screen reasonably easy to read when it is mounted on bike handlebars?
