I wouldn't give any more money to Bezos he is already the world's richest man. I have a feeling TTer was talking about TRP but anyway the above kit will solve all mineral oil brakes or at least all the major brands you are likely to deal with.
They also do some nice stuff with their
barb tool but that one is maybe more than you might need for most things. You might also want something to true rotors with if you feel comfortable with that.
