Hey all, i've been thinking of taking the scaa BEST classes for machine repair. I have some general knowledge from doing maintenance for the last few years but kinda want enough knowledge to do an overhaul. I would like to get a position as a tech but probably won't move to it permanently. So the question(s) is (are) would the high end classes be overkill for my simpler aspirations? Are there other certifications i can get that would be as comprehensive?
