I have the Atlas AT50, which I like. I added the horizontal and vertical "wobbler" motors, and placed the whole thing on a small 40" X 48" trailer. There is room for the battery, cables, and a couple of boxes of clays, and I can tow it with my ATV.

You can set the throwing angle fixed anywhere you like, and the H & V drives can be activated either by themselves or at the same time. Since they are not in sync, the throwing angle changes every throw.

I am very happy with the setup.
