But that goes for sales people in stores as well.
So general rule would be to trust your own judgement and common sense.
But some purchases we do will not be up to expectations - and I call that "education money".
And there is where OP makes sense - just get cheapo something - and if not up to expectations your loss is not disaster.
Schooling is part of trusting experts - when I started grown up life at 20+ I realized that I was fed all this about "experts" and "science research" and as coming closer to 30 I realized these are just opinionated people too. They often have an opinion in fields there really is not their expert field. Especially when it comes to things related to politics. With a professor title they can claim knowing anything, and they don't.
Just gotten my first Strat I was browsing through YT a lot about setting up tremolo. And one from PremierGuitar.com, one would think they knew one or two things - I found total BS. He was stating something if wrong is bridge is lifted at back from body, and put strain on guitar and whatnot - well, that depends on if you have it setup as floating or not. So there we go.
Never trust one source alone - check out many sources - and trust your own common sense.
Same with sales people in stores, and YT stuff from stores as well - they are all about selling stuff they have batter profit margins on.
A couple of years ago I looked for acoustics a lot. And one store on YT totally bashed everything else at that price range because they did not have dove tail neck joints. That was the sales pitch for him. Not that it sounded so much better - just about the dove tail that you have to move to Martin D18 to get.
I don't think Taylor have a single model with dove tails, as I recall. Must be crap then.
Especially young people just leaving school should have the confidence to trust their own judgement and being able to navigate todays world with such a broad range of information. Not to trust any expert because of a title, they are just people.
