Others with more experience that me should feel free to correct me. But in my limited experience, that tool is fine for the 50A andersons. It looks exactly like the one I have.
The non-insulated terminal die is fine for the 15A Andersons - you just need to be careful to orient the lug the right way round (don't try to crimp the side with the slit - it will just open up).
If it were me I'd buy a $20 tool for the Andersons and the Rhino Automotive Ratchet kit for $90 and see how you go - you can always pick up one of those hydraulic crimpers later. I cannot see any difference visually between that Rhino tool and the Toledo - even the markings on the case are identical.
