I just got my H9 and I love it with my iPad controller. But I do agree that the $20 price for each algorithm is a bit high. We do get 1 free purchase. I have the PitchFactor as well as the H9.
If these were $10 I probably would have bout 3 or 4 by now, but at $20 I have not bought any or used my credit. Now I don't really want to take a chance on getting one unless I really think it will be useful.
