For $(removed), this is a really good starter kit for getting to know the Arduino electronics protyping platform. It has an Arduino Uno clone, a bunch of resistors, a capacitor, a photo resistor, a capacitor, pushbuttons, jumper wires, a speaker, a solderless breadboard, and a shift register integrated circuit (handy when you need more output pins than the Arduino supplies – see this tutorial).
