The setup thing is no joke. I made a sub $200 mandolin play well out of its league with just some sandpaper to lower the nut height. I still got the nicer one but for the time inbetween it was great. Now the friend I bought it from for $50 has it on loan since she can actually physically play it now with the lower string height.
I’ve learned that the ROI on most expensive stuff just isn’t really there unless you’re deep into it and want to treat yourself or you’re a professional(which is kinda the same but I’ll keep it separate). The caveat of course is that you have to start at a semi-reasonable place like you mentioned.
I don’t know why we want to believe that the high-end stuff is made with fairy dust and that we’re not capable of these things with just a bit of effort and trust in ourselves.
