For most hobby use, it can be argued that it is is not necessary to buy industrial quality tools, for relatively low useage, that super accurate tools provide.
It may not matter if a taper is out by a second of arc or two.
(Matching internal and external tappers can be produced, by not disturbing anything between making the cuts).
But they may not EXACTLY match other tapers, such as Morse Tapers, (But careful setting up, using an existing one as a setting gauge should overcome that problem.
Again, the choice has to be between paying a lot for greater than need accuracy, and the cheap and nasty. You makes your choice and pays the price
