I have used an ATN for several years and other than its controls, which are not particularly intuitive, it has worked perfectly. I can identify species out to nearly three hundred yards and it will easily handle a shot to two hundred. @gizmo has used them pretty extensively in his operation in North Texas.
My favorite, however, is my Leica clip on. Not in your budget, but something to consider eventually. I simply clip it on the scope of any rifle with the correct size objective for the mating ring, switch it on, and head out the back door. It is 640, so when combined with German tech, it is an amazing device.
I have an ATN monocular for scanning while calling or for finding game as @mdwest suggests.
