After maybe 250$ of trial and error, I found my favorite vendors and stick to this only. Now I rarely buy anything new except non essential stuff, when it's my birthday or something.
I am with you. I only wish you could resell the ones that didn’t work out.
I’ve stopped mostly in the past 6 months, but have a list of a few I want, but it’s gettinf to the point of what else can I get that sounds new, different or better than what I have.
