I can only speak of my experience, I bought all of my tools individually. I have the Coil Master 521 Tab and have no trouble at all with it and I have used it for the last 4+ years. It isn't just an Ohm reader, it is a very stable platform for building, installing, and testing your coils. You don't need a pair of wire cutters, a pair of toenail clippers will do nicely. I also picked up a pair of scissors at a discount tool store and have also used them for years. I have wrapped my coils around a 2.5mm machine screw and have gotten great simple spaced .5Ω coils. If my Coil Master broke today, I would not hesitate to replace it. I know I can test the coils on my mod, however, using the Tab as a platform to me is very important.
