Not offering advice on purchasing an AP, but if you are interested in trying to get more life out of this one:
My guess based on reading the article is that it's mostly logs filling the disk. You can find out for sure with some version of
du -a | sort -hr | head
Then just start deleting logs at or near the top of the list - I suppose this would get you back running. Sure, constantly writing to logs sounds terrible for performance, but did you even notice when it was working properly? If it's actually Ubuntu running on this router, you could even install (or configure if it's already there) logrotate to probably prevent this from happening again at all.
Then you still have a POS router, but one that might get the job done.
