Throwing good money after bad, you are free to do whatever you want. I have seen the prices of Apple Offical Support it is often cheaper to buy a new phone than what Offical support charges you to fix yours. It is all part of the Apple world, You pay a lot for it new, when it fails as some of the recent ones due quickly, lots of broken screens, the official repair is close to 50% of the cost of a new phone. How about $300 for a new iPhone 12 Screen, I can buy 2 Moto G Stylus phones brand new with a warranty for that. It 's your money spend it on what you want, hell pretend you got a good deal, I don't care what you do with your money.
BTW fan boi, what models of Iphones come with a built-in Stylus?
My Moto does and they are new for less than $150 unlocked. Yes, I use the stylus often, my hands are pretty big.
