Metric Screw / Nut Assortment?

Anybody got a favorite metric screw (phillips head) and nut assortment from Amazone they’d recommend? I’m looking for a good variety, primarily in the M3 - M4 range. Lots of options on Amazon, hard to find the “best” one…

I don’t. But I will mention that boltdepot.com and my local ace hardware have good quality metric bolts. They aren’t as cheap as an assortment, but I have most already, do I only buy what I run out of, instead of all the sizes.
