I want to know which of these two systems is better for the following senarios. I am going to Iraq and I want a good mapping gps unit even if all I can get are topo maps of the ares, and I also want a good system for geocaching when I return home, or if I deside to post one over there somewhere (pretty extreme imo). I'd also like to get the better system of the two in duriblity, reliance, and features. I can get the Legend for 160 , and the sporttrax for 170 w/ 30 mail in rebate. I am leaning towards the sporttrax because my buddy bought one yesterday and we can share mapping programs, plus the rebate is nice but I have heard bad things about people not getting the rebates, What is my best bet?
