just ordered one of these and would like to see some reviews from owners of this unit, i went with the 450 instead of the 450t so i am also looking for opinions on maps or whatever i should download for it (i know there are alot of free ones out there) or if i should just pay the extra 100$ for the 24k maps. its primary use is gonna be for hunting, pretty much just to mark where i park my truck or camp or whatever so i can navigate back to it incase i lose my way so i am not sure i really need any extra maps for that purpose. later on i might be wanting to get a little more detail out of it like creeks and trails and such but for now its only purpose is to keep me from getting lost. i will be doing most of my hunting (atleast this year) on the westside. i know i am a little backwards and most people search for reviews before they buy but it is what it is. i should be receiving it on tuesday and i am gonna test it out next weekend while i am camping in hood river.
