Don, I got mine off Ebay from China for approx AU$115. It can be bought off AliExpress for a few $'s less. I initially thought it's a bit expensive for a breakout box but I've changed my mind since using it. It's well made, the activity LEDs are excellent, voltage display is useful, there's even an LED light on the OBD plug to help locating the socket in the car.
