Hmm.. I just bought a H9 standard, and I now see that it will require 20 purchased algo’s to convert to max, and not the 10 that was previously required! I guess I will sell it, and get a used max. That will be considerably cheaper than buying 20 Algo’s for another $400.!. so despite getting a good price on the unit, it no longer seems to be a bargain, in the long run.
