The price is what you think is fair. You can always donate more later I suppose.
Normalizator is if you don't model and just use texture manipulation to create your maps.
When I use quixel suites, I need to burn a color id map for material separation, Normal map from a high poly mesh, AO map at a minimum, to get the needed results.
This program is like xnormal, but looks a bit more easy to play with.
If you do have a model program you can bake your textures inside the program and would not need Hand3d. So it depends on what workflow and skills you have.
I had just run across it in a post in the quixel facebook page and checked it out. Looked interesting and for a small price of your choice you can be baking maps you need. The video I watched looked like you can bake all your textures. Baking multiple parts at the same time without them getting mixed together seemed like a bonus.
