I bought a cheap bbkt tap set from AliExpress (maybe $80 three years ago) it's been fine for the few times I've used it, in both aluminium and steel. If you're not sure that a thread is straight, the tap holder aligns the two sides very accurately so you're sure it's not crossed, something that most DIY solutions aren't going to do. Used with a proper metal cutting lubricant, it's a quick and easy way to tidy the shell threads before fitting a new bottom bracket.
