I like the garmin Oregon. Fairly big screen, has a camera though not as good as a cell phone camera. It's cheaper than the garmin Montana. Memory card enabled. I have onx on my Iphone but isn't that reliable as it craps out (battery dies) in cold weather and no cell service many places I hunt. I really, really like having the onx private land info on my gps so I buy the chip too. Though as long as your GPS shows public land boundary you could get by without a chip so long as your mapping info is good. But there is a lot of use full info on the chip like forest fire burn locations, logging info etc that generally isn't on a topo map. Nice thing about onx too is that you can view the same map info on your computer and print a physical map out with your own waypoints etc on it and have it with you on the hunt. Sometimes it's just easier to look at a physical map and see the BIG picture to help you adjust your hunt more quickly.
