I use Kdenlive most of the time with a little mix of OpenShot every once in a while but I run Linux on most of my computers. Ubuntu on this one and the desktop out front I have set up to double boot unto Ubuntu or Windows for the extremely rare times that I want to use a MS Windows program. Ubuntu Studio, KXStudio and Ubuntu on a laptop I have set up to triple boot. I have other computers that I have running other versions of Linux but I just play around with them and don't use them much.
I pay $0 for all this software.
