Depends on what you are looking for. If all you want to do is read and clear the generic OBD II code list buy the cheapest code reader you can find. If you want that as well as reading Porsche specific codes,and be able to reset the pesky airbag light, as well as read and record all of the engine parameters, like fuel trim etc. get a Durametric. I have both a fancy generic code reader that does read, record and graph generic OBD II values, and then I have the Durametric that is Porsche specific. I'm not sure where the generic code reader is...
