Unfortunately I have never seen a really good tap & die set that was worth the money listed. Finding a complete set that meets all of the needs for our hobby prebably does not exist. I have found some cheap sets that carry most of what we need, but purchsing solid replacements along the way have yielded even better results buying individual taps and/or dies. It will certainly cost more to do it that way, but you can buy much better tools that way as well as pick & choose quality pieces. Good luck wih your quest.
Try this one.
