Where can I get dirt cheap servos?

  1. Mar 12, 2012 #1
    I'm tired of blinking-LED programs, so I figure I'd experiment with a shift register (74HC595) and after reading about it a bit, it seems like I can use 3 of them on one arduino to control 18 (24, actually, I guess) servos.

    the magic number is 18, since that's how many articulation points are on a hexapod.

    anyways, the cheapest I can find is 2.65 each, which still puts me at almost $50 for motors alone! After additional hardware, the platform could be pushing $100, which is more than I want to spend >_<

    can anyone beat that price?
