I had an Atlas, 600 I think. Piece of junk. Had to be on maximum spring tension to get any reasonable throw, and then the spring failed quickly. Bit the bullet and got this used Lincoln for 2500.00. I know that's way out of your stated range, but this reliable commercial thrower has transformed my shotgunning. Holds 400 targets and is reliable as death and taxes.
If you just can't spend that much, try before you buy. I would have never bought the Atlas had I taken a test drive. Here is the Lincoln at the property yesterday- sitting on a bluff, I consistently get 80 yd throws. I have transformed the handheld button into a foot switch, as I am often shooting alone. With 150 ft of cord, I move around in relation to the thrower to work on any presentation I wish, except rabbits and chandelles.
I thought about a remote, but I would still have to press a button with one hand,
put it back in my pocket while I fumble to mount the gun. For me, the foot switch rocks.
