The only one you mention I have experience with is REI.  I wouldn't buy one again.  I put a REI model ST-1000 in a tractor 2 years ago and it is already dying.  It functions, but it occasionally changes volume spontaneously when hitting a bump.  It actually thinks the knob is turning as the volume indicator on the screen goes down.  Also, sometimes when turning the knob up by hand the number goes down, then up.  Really poor stuff in my opinion.

My go-to radio for farm equipment is this one:

I've got 3 of them in various machines and they have all been entirely trouble free. Even put one in my farm pickup.
