I'm not a professional, and I have and use one of these. Running film through the camera will not tell you what a shutter tester will tell you. Since I perform my own CLAs, a shutter tester is indispensable. So too (indispensable) is the ability to test a shutter without wasting film, which in the case of 8x10 transparency gets expensive rather quickly - $27 per sheet in the case of Fuji Velvia.
