I like my Garmin Oregon 650t. I've used it for trapping and hunting, marked lots of spots with it and and it's never failed. It has a camera which is kind of a nice feature. Screen and unit itself are perfect size in my opinion. Clear color screen, durable (have dropped mine a few times), pretty quick to launch the different "apps", and it accepts an Onxmaps chip. What else are you lookin for?

I hunt and trap alone the vast majority of the time so I haven't really had much need for the walkie talkie capability included in the Rhino...
I just use the Garmin caribeaner that came with it...clip it on my pants belt loop and I can flip it up to use it without having to unhook.
I think you can probably try the ones you're interested in at a store before buying?
