Not a proverb; just an observation
Join the EEVblog TEA group; they will help you with your problem:
Help point out test equipment that you don’t have but suddenly NEED
Help by pointing out sources of obscure test equipment add-on modules and accessories to make your test systems complete (if that is even possible)
Help by setting the bar high for sheer number of test instruments
Help you find excuses for why you need more, more, more
Help you answer the inevitable spousal question, “What do you need that for?”
Help guide you through the labyrinths of the test equipment rabbit hole
For your foray into this great camaraderie, just post your problem to the TEA thread of the EEVblog where you will find lots of kindred spirits to help you feel better about your addiction
