Or you can do what I did and buy the three parts here on Amazon separately...  The wax motors are $8 each. The resistors are $1.50 for a pack of 10 and the triacs (improved 600 volt versions) are ten for $10 or a buck for the triac and 0.10C for the resistor.  Why is this "kit" $56?  Overpriced by at least $40.  For $18 total I got the motor, resistor, and triac and have 9 extra resistors and triacs to boot..
