This set could be one of the lowest prices on Amazon. It has LEDs, LED strips, piezos, potentiometers, an Arduino clone, an LCD screen, a joystick, an ultrasonic range finder, two keyboards, two servos and a motor, and it just keeps going. I've just ordered 3 more of these just to replenish my inventory at the home lab!
