Which code reader

[Black VXR]

I have a 56 plate 2006 6.0 Monaro - I am thinking of buying a code reader - which ones work, any recommendations please

I am thinking I don't want to spend a whole lot of cash but I guess there's no point in buying something that doesn't work - like the guy selling cheap parachutes who says, I have never had anyone come back and complain...
