I have been thinking about the merits of Garmin’s new eTrex 10 for a while and decided that it is not worth the money - £100 at Cotswold 28122012Alternatively, a brand new eTrex 20 is £80 more than the eTrex 10 at Cotswold, yet offers so much more than the 10, because it has on screen mapping (£20 of which comes with the unit).
