OTH people who want to buy strat would prefer to buy "strat with all inherited problems already fixed", be it PRS silver sky, or any boutique brand like LSL / Sandberg / Suhr / Tom Anderson.

> would prefer to buy a Fender strat

I don't think that's true at all. A strat ("strat style" or "s-style") is a shape and configuration. Many of the non-Fender strats are perfectly fine guitars (I have one) from major manufacturers like Ibanez, ESR, Jackson, and others.

A lot of it is also the history associated with all the strat cats from the 1950s onwards and really good marketing by fender, you're buying a real strat because you want to be in that company (Buddy Holly to Gilmour etc). I recall only wanting a strat when i was in my wannabe-yngwie phase. nothing else would fit.

Fender makes a whole series of Strats at different price points. The challenge is even at the high end Fender has inconsistent QA, so the 'knockoffs' are sometimes way better quality/consistency. See this video for more info: https://www.youtube.com/watch?v=OU7RUpkXsV0

I'm looking at buying one now and as far as I can tell Fender seems to make shoddy quality instruments these days. I see a lot of recommendations for PRS and others.
