Is the Garmin Vista the one with the full colour screen and full orientation? ie you get an idea of what's around you rather than just following a line?
I was thinking of getting that. At the moment I have an edge 305 which is really good if you stick to the preprogrammed route but if you have to deviate for any reason you need a paper map with you. Having said that i always think it's good practice to have paper maps and gps because the technology aint always right, and sometimes the info presented to you needs interpreting.
For LeJog just buy a road atlas, and a set of highlighter pens. Mark out your route on the back lanes, and then cut/stick it together with sellotape and scissors! Job's a good'un.
