And which small country? You could look at OpenStreetMap: http://www.openstreetmap.org/ Firstly, some of the roads may already be mapped (depending on where it is), and you can download the data to do stuff with. Second, there's plenty of advice on the wiki for recommended GPS receivers that are good for mapping, as well as suggested mapping techniques etc. See http://wiki.openstreetmap.org/wiki/GPS_Reviews There's a variety of GPS dataloggers that will just record a track of where you've been. Or if you want something that can display maps, something like the Garmin eTrex Legend HCx is a reasonably priced option. -- Craig Wallace http://craig.neogeo.org.uk http://www.neogeo.org.uk
