Rough price estimate is 70$ each but we need to be 30 or more buyers.
Myself: 6
Sinuko: 2

Work in progress ... umpf ... 96 resistors (well actually 93 as I am missing 3 Rs) soldered.
Find the XLS file I made to calculate the ladders. Don't mess with the cells, you can modify only the dark green cells: ladder impedance and dB steps.
