Yes, A4988s can be had for $0.50
The A4988 is an OK performer (no vibration), but being limited to 1/16 max, it is less flexible. If you need 1/32 (per the spreadsheet), you are out of luck. As you say, there are better options out there, for not too much money.

and DVR8825s for around a buck
The DRV8825 used to have an advantage in that it can drive more current for more torque.
But it is notoriously shaky, and inaccurate too.
No one should use it for new builds.
