Last couple of weekend have seen me out exploring paths and tracks in Surrey and Somerset on the bike. I think I may not have spent as much time slightly lost if I had had a decent gps with maps with me so am considering an etrex 20. It seems to get good reviews but is there anything else worth casting an eye over? It would also get used by the Mrs hiking in Ireland hence moving away from bike specific ones.

I like my Oregon 600. Bigger screen, easier to control. Does bike functions (like cadence) too, though I also use it for hillwalking and rafting/kayaking.
