I can totally relate to this...
Used to make me so happy when I'd be able to scrape up enough money to add something new to the car, but now I'm just sick and tired of ending up with stuff that is either total junk, the completely wrong part, or in pieces by the time it gets to me.
I'm back to using original, used, or 30+ year old aftermarket replacement parts.
People say all the time "Ain't it great that there's so many reproduction and replacement parts available now?"
Not if they're all crap.
