So far I've only used Rep-Cal's assorted items, I'll probably test another brand after, although it works great for me. I have Calcium (with d3 and without), and a multivitamin. Honestly, most frogs aren't too picky. My pacman frog is my most picky, and he eats with or without dust, no problem, as do my tree frogs and toads. I think it'll be fine.
You might want to make a new thread asking about brand comparisons and experiences, and maybe availability.
