I would like to point out that Zorro is currently in the price range of programs such as Mathematica (where you can get a permanent license for just a couple hundred bucks under certain conditions). Functionality density and stability of Zorro compared to Mathematica is night and day. The least a developer could do is have the program development process certified with an official industry standard if they want users to dish out this amount of money for it. - Or, drastically reduce the program cost to emphasize that it is just a "hobbyist, freelancer" effort. (And note that I'm not asking for myself, since I already dished out over 700 bucks for Zorro S.)
