correct, get a quality set, they break easy enough without being made of inferior trash.
Shop around, paying cash on the tool trucks (if you have them available to you) goes for making a better deal. Matco and Snap-on pretty much have the same set, Cornhole probably does too. make 'em price match.
I bought my set from Matco on sale for $179, made by Hansen, branded Matco. regular retail was $230. even with a "Set" there will be taps that aren't there that you'll need cuz you'll never know till you need 'em.
be sure to get a set of Tap "flute remover" extractors as well, for the time when you do break a tap in a place you really don't want to have to disassenmble.
