Most tattooers have drawers full of coil machines that they may have used a week or less, that is how I looked at it when I purchased my first rotary. I looked into my drawer and saw the money I had wasted on many top shelf builder's coils, that I have used on only a handful of tattoos, and realized I had made much worse investments before. I was also afraid that a cheap rotary would have only detered me from sticking with trying anything more expensive if it weren't performing for me in the ways I expected.
