I'd forgotten about another one of the budget grinders - the Varia VS3
This one uses a conical burr system instead of flat burrs - similar to the wildly popular Niche Zero. Will be fine for AP/FP and also espresso. Not sure how it fares for espresso cos haven't tasted myself, but for Aeropress and filter, the quality is below the DF 64 (with specialised filter burrs) and about on par with the DF 54. But this one better built.
Also, this is a stepped grinder while the DF 54 is stepless. So it is easier to remember grind settings and go back to them with the Varia. With the DF 54 you have to fiddle around cos there are no exact markings or notches
