Garmin Oregon 450. Main criteria was that it could use a chip. I, too, picked up the onxmaps chip for my state and it is a welcome addition. Rather than wonder who owns what land you know immediately.
This year alone I've gone places I wouldn't have without knowing exactly which property I was on.
The gps on the phone is better than I thought it would be. However, unless you are thinking ahead to get the maps while you can and are in a spot where you can charge the phone, I like the dedicated units because you can replace the batteries. The touchscreen on the 450 is nice. But I would be happy with a 62csx without it, too.
Love the gps!
