Secondhand Ruckus APs are a pretty decent alternative, you'll have a hard time getting AX gear for a reasonable price though.

edit: Secondhand Ruckus/Brocade switches are solid, at least on the 7000 series the evaluation key has no time limit so you're not license-limited in what you can do with them. Switches are mostly <$250 on eBay if you're buying an ICX7150, ICX7250, etc. Yes, that includes PoE models.
