Another Diagnostic Q

Evening all,
been looking all over the forum and read related posts regarding EAS faultcode reader & clear units for my 2005 L322,there seems a lot more choice than I first thought, Im in the process of buying one of these and could do with a bit of direction...Ive looked at the Hawkeye with the option of the air suspension lead and I reckon that Im looking at about £350.
Seems to tick all the boxs for what I want and just want the nod really from the experience members out there on this being a worthy purchase.

Thanks Chris.

Allcomms from RSWsolutions is a good bet and fairly low cost, but if you want the bogs dollocks it's got to be Faultmate from Blackbox Solutions.
