Looking for GPS recs. I'm looking at the Garmin GPSMAP 60Cx and eTrex Legend HCx.

The primary use is for geocaching but I want to be able to use it as a car nav in a pinch, though my iPhone and Google maps is usually enough. I want easily added maps, so memory card options are a big plus. I also prefer the newer GPS chipsets (SiRF Star III), so I'd prefer "newish" units vs older stock ones.

Thanks!
