between the high end stuff, AST Retriever and the LED/Sw combo (biuld it yourself) DIYer tool.

The Retreiver costs $2300 making it, to my mind, a high price tool. Would love to have one since it can do LIVE data, reading the S/A (self adaptation), firing/mis-firing, O2, MAF data, etc.

The PS just reads and resets codes from 1988 thru 2002. It does not do what any LIVE data. I'm sure the SnapOn device probably does that but not familiar with it.

Actually, the newest/latest versions have added such goodies as a 'scope' which you would appreciate. Then you could "see" the misfire. But if it is failing (even intermittantly), the Retreiver would catch it in the LIVE data mode. But for me, the price is just too high.

I would stay away from just OBD scanners as Steve suggests; if it can give Mercedes type codes and OBD, then ok.

I've use the PS and it's a good tool taking its limitiations in mind. The PS is great deal for the price (send me an email). Depends on what you NEED to do.
