Thought I would give you guys a heads up that a publilc beta of Affinity Designer is out. I've been tinkering with it. It supports Pantone and CMYK. I don't now how much it will cost in the end, but the mac version costs £39.99, a bit over $52.00. Could be the Brexit brought the price down.
This is a better link to the download as the main download page as a one version older: https://affinity.serif.com/forum/index.php?/topic/23086-affinity-designer-public-beta-1508-windows/
