For years (since 2004) I've used Paintshop Pro Version 9, the company was bought by Corel, at last there's a new version I like Paintshop Pro 2021 which I bought around 2 weeks ago.
I've also used Corel Draw since version 3 in the mid 1990's which come with PhotoPaint, this gives me the opportunity to get special offers and upgrades at very reasonable prices. I've found After Shot 3 Pro is excellent (for RAW images) and BenVista Photo Zoom Pro 8 brilliant for resizing.
