tap and die set?

I bought the northern tool kit about a year ago because I needed a couple of large taps and it have everything from 1/4 to 3/4. While $100 is not cheap, a full set of ultra height quality mcMaster taps will rind you about $500 for the same set. If you are doing a lot of tapping in a machine shop, then go for the high end stuff, but for an occasional use in a garage, then the cheap stuff is ok, I also have a set of HF npt taps, and a set of 1/4 to 1/2 high quality taps if I'm tapping some hard stuff or chrome moly. It's also a good idea to have a set of bottoming taps for engine work.
