Hello everyone, my first post. I was on the Nissan Titan forum that i frequent often and someone mentioned geocaching. One look and i am hooked. I am looking to buy a unit and am considering either the E Trex Vista C or Explorist 400 which looks like it may be available mid feb. I have looked at the site and see that the magellen/Garmin groups are passionate about their units. I already have an Ipaq with Navtech jacket running pocket copilot 5, so i don't really need road mapping capabilities. What i like about both models are the new geocaching features. My question is with only geocaching requirements is the 24MB of memory on garmin sufficient, nowadays, 24MB doesn't seem much and i worry i may lose detail over the SD option on the Magellan. Any thoughts would be appreciated.
