I haven't tried Affinity products, but in recent times, I have started actually buying software.

I realized that I am willing to pay around 60$ for a marvelous editor (Sublime Text) or audio recording program (Reaper), in a non-subscription model, with non-cumbersome licence handling. I wish there was something similar for CAD software - something like Fusion 360, but where I can pay 60$ and be sure to be able to use it for the next 5 years.
