Welcome. As you read the forum posts you will find that most here do no rate certifications high on their agenda. Reliability, good writing, and objectivity in reporting trump certifications every time in non-video shops. for video, training can be important, but that can be had at little cost, on-line, through IMSC. MSPA mainly represents the MSCs as a lobbying group, but not so much the shoppers. To make more money I suggest learning video and saving membership dues to buy an acceptable video recorder and camera. Currently, that would be a PV-500 with upgraded button camera.

Have video cam; will travel
Poor customer service? Don't get mad; get video.
