IMO Quality tools like ifixit are worth the premium price as they should save you time and frustration. I learned this very quickly when I was a teenager working on cars, computers, house projects, etc with inexpensive crappy tools that broke, stripped nuts and bolts and generally made for frustration and wasting time.
It's better to buy 4 quality tools that will last a lifetime and perform well than 16 crappy tools that break or dont fit right or frustrate you. Cheers! ?
