I certainly have more indicators that I will every need, but not a big collection. Some are more useful than others for specific jobs or on certain machines, others are spares in case another indicator develops a problem, which lets me move right ahead, not keeping the job waiting for a repair or a new substitute. Occasionally I use more than one indicator at the same time, which can save time. I purchase one that is up for sale when I can see a particular use for it, and it is in good working condition, or has a issue I think I can repair without too much fuss or cost. When we are not in a big hurry, or can often fix them as needed, we can also take our time to find better pricing. There is nearly always something on hand here that will do the job without having to wait for one to be repaired or purchasing another one, which usually ends up much more costly when we are in a hurry to get the job done. Most indicators do not take up very much storage space in the shop...
