do you buy car diagnostic tool

[Naiqutter]

I am looking for one scanner to do injector check of my jetta 2008, I just bought this used car. Are there any differences between the original tool and clone tool? Not to say the price...
I found the Fcar scanner which for diesel car

is it clone? $1800, this price seems not "clone"
How is this one? are all the online seller selling clone tools?

You can get a personal license from VAG with an activated cable for less than $300, which is the best tool I've found to use on the cars.

Ah..
I do found three obd2 cables, but none of them mentioned can work with diesel car.
This one is only $60. viewtopic.php?f=8&t=11618
and $12 http://www.uobd2.com/wholesale/obd2-cab ... -3299.html

But there are no detail about how to use these stuff.
