Drawplus X8 is only £20 / $25 and there's a discount coupon you can use for 25% off: DPSURPRISE
I'm actually tempted by it, even if I've bought Affinity Designer, exactly for the AutoTrace feature (I'll just convince myself that I'm paying for a plugin, I suppose). A bit reluctant though, as I only had problems with the last version of DrawPlus I owned, think it was X5, maybe X6. It crashed all the time, and was pretty much unusable (for me, YMMV). The software was very nice, when it came to features, GUI, etc. but the crashes, not so much
There's of course also Black Friday and Cyber Monday coming up, so there might be an even better deal coming up, for all I know.
