I hear you about the price, not budget. I started this as someone in the photographic community( repair cameras and lenses) but a complete hobbyist. I started way back with PS7 and used it until the cloud rental was pushed by the A company. Switched to Affinity and was hooked. Little bit different, but not that much. I was sorta upset because no upgrade was offered, but when it went on sale I jumped and haven't looked back.
YouTube has definitely changed learning for the better. I watch James Ritson, Olivio Sarikas, Robin Whalley to mention a few> The big deal for me is the compound masks now offered, truly neat once you figure it out>.
