Some forum member appear to enjoy writing long overburdened posts with no clear objective other then to stir the pot. These members will often take a negative stance toward the topic regardless of the discussion. My recommendation, take these comments with a grain of salt and enjoy what the forum has to offer.
In my experience, it is far better to offer our very few and proven upstanding aftermarket parts supplies the benefit of doubt rather then alienate them with questionable and broad possibility comments.
