WTB Knock sensor

[AUSVR4]

Hi guys,
Where can I get a knock sensor for the VR4? I know Meek sell them and I don't want it to seem like I'm bagging them, however for the price they're much cheaper from the US.
Is there anyone else in Aus that sells them and has some in stock?

Also, what's the difference between the 1G and 2G? They have different listings and prices but RRE have this to say:

Knock Sensor
The 1G knock sensor is a miserable sensor. You really need to switch to the 2G sensor. The part number is MD300670. The wiring connector and threads are the same, it is a direct bolt in. The 2G sensor is much more communicative and linear.
