Exactly this. The amount of time, effort, labor, sourcing tools, parts, coupled with education, or making a costly mistake, etc... The warranty or repair person is actually cheaper if you're able to put a price on your time. They also do better work in most cases. I just leave it to the professionals because it saves me money/time. I have no doubts I could do my own repair but from this vantage point it's just not a sound investment.
