My friend Bree's strat copy (she bought it from a pawn shop for 75$) has high action, and she didn't mind it for a while.
However, she had told her dad about it who is a carpenter. He researched some common, not too expensive tools and told her that he would like to try setting it up. He and my friend have read and watched quite some videos, trying to prepare for it.
He read articles like this one:

He has been doing good quality carpentry work for almost a decade. If the guitar doesn't have a major issue, should they attempt it? Where should he start?
If it doesn't work out, he will buy her a birthday gift of 200-250$ strat.
