You have a point. FanDC is 1300 euros for the TOP source package.
Well it is true that it is free, but starting from 0 will be kinda a pain in the ass, not impossible, but will take a lot of time to make all the stuff. They are atleast very active in their area about fixing bugs. The other ones aswell, but Im not saying it because Im not a premium on their forum so I have no idea about their timeline activities.
Even if Scripts was better, it is still a no go. Their price marging is too high. In the future perhaps...
