i made my chase for the brand : Garmin

i am in doubt between 2 models :
the eTrex Venture
the Geko 201

i made a comparison between the 2 models which resulted in this

the price is about the same (also in local shops in my town or nearby)

advantages of the etrex :
- the etrex can run for 20 hours / the geko only for 12
- the etrex uses AA batteries / the geko uses AAA which are more difficult to obtain
- the etrex has 4 shades of grey while the geko has only black and white

advantages of the geko
- the geko stores 125 waypoints per route / the etrex only 50
- the geko is slightly smaller and half the weight of the etrex

i dont know about the importance of the other differences

i especially like the longer lifetime on the etrex ... but i dont want to give up 60% of my waypoints .. i think

does anyone has any suggestions ?
