So I bought an Instant Vortex 6 qt air fryer. Used off Amazon.ca for $125. Although it was classified as "acceptable" if the box had ever been opened the unit itself had not.
Made fries in 11 minutes total (2 min preheat, 9 min cook). Usually take 22 min w/o the preheat. No need to put things in a single layer. I'm sold.
Only downside: The thing's loud. Needs to use Noctua fans.
