I would pay for this. How much depends on the package and it's features. Will we get a Shape-editor? How much additional coding is required to achieve effects I want? Will we get the sources?
E.g. I bought ParticleCandy ages ago. It worked perfectly but I ran into many situations where I needed to check the source and change something. And it was great to have the opportunity to do so. Without sources you're always forced to use it the way the author wanted.
So getting the source is a major argument to buy something (at least for me) and I would pay twice as much as for a package without source. Another benefit of this: if for some reason the author stops support, I can add features/solve bugs by myself.
