Just my .02 -
We have an Explorist 100. It has worked flawlessly and it is easy to use. I do have to enter coordinates manually, but I'm also saving money doing so
What I do is copy the info from the cache page and paste it into word. I then print this info for all our caches. Then, I sit down for 5 minutes and input the coordinates. It's not that hard...
If I was buying today, I would get the Explorist 210. I wanted the 300, but it's not much better (for me) then what I have now.
