I'm a seven or an eight. I can take apart and repair most things, I only run into problems when soldering tiny things off of a commercial board comes into play, mainly because I don't have a decent soldering iron. I may not know that the matricating hyperflux dematroogulizer is what the little yellow thingumy is called, but I can (usually) tell that the yellow thing is the problem and order a new one. My buddy Tony does all the soldering though. I'm all thumbs.
