I used my 450T in Colorado & Wyoming last year. Dowloaded the huntinggpsmaps for each state, and they proved to be an excellent reference tool when hunting public land!!! To me, the cost was well worth the benefits, especially for a non-resident unfamiliar with the territory.
I also have e-touch gloves, got em @ EMS and they work fine with the 450T's touch screen and my dog's Alpha unit.
Great unit, good luck!
