I have a set of Vermont American taps and dies that I have been very happy with. The are at least fifteen, maybe twenty years old. Can't remember for sure. I got them at Ace Hardware. They lasted through my automotive repair career and are still going strong now that I have my "machine shop" in my garage and use them quite frequently. I have not had any of them break, but I find I'm not as hard on things as some. I also have some Snap-On taps and dies that have not disapointed, but again $$$. Just use cutting oil. It helps. A lot.
