There seems to be a shortage of the TMC5160.  I paid $17 middle of last year for a Bigtreetech TMC5160 V1.2.  I believe they are up to V1.3 now, and I do see them from $30 to $47.  Khalid mentioned external drivers, I bought one of these on Amazon for $10.

Generic Step & Dir controller $10:

TMC5160 V1.2 Ebay, $58 for two pcs.
