I’m in same boat. Turnaround is awful for anything besides the most basic boards, and that being fast doesn’t really help when it’s just quickly entering a slow delivery process.
I find pricing really scattered everywhere. Often mouser and digikey, which others swear by, have worst pricing (and availability). But I think these places are intentionally high on some items to discourage production runs and keep it a prototyping service. Not sure why they care though.
As far as I understand, Arrow is where you go when you need larger component batches. And if you're too big for Arrow, you probably already have a Chinese manufacturer in the works.
Also, really take a look at JLC's component prices and compare them. Some of their markup, namely for ICs, is borderline criminal.
