Hi All, Brand new and want to get started cacheing, but need some good advise on what GPS to get. Have read some on the various units, but so confusing. What are the basics needed? Topographical? street maping? WAAS capability? Also have an IPAQ,I could get software for I think, but wouldn't be waterproof. Also, travel Asia and Europe so would like to be able to possibly find some caches there. Any help would be appreciated... Thanks
