I'm not a fan of modeling in Blender, but now do all of my renders in the program. As it's a free program to download and use, it relies on the support funding of its user base. In this respect it's important that any user of the program consider donating a few dollars to the fund. You can donate any amount you like. The number of users donating is very small and I'm sure no user wants to see this program fade away because of a lack of funding. I don't make a single cent from the models I create and render as that is of no interest to me. So if you can dig out the odd dollar or two the Blender Foundation would be grateful for your donation. This is not my first donation to the Blender Foundation.
