I usually am not very fond of harbor freight tools unless I'm getting
something I know is a throwaway, but I'll have to say I have been impressed

That big set in a metal case with all the fractional and letter sizes for
about forty bucks is surprisingly good.

I use an iPhone app to figure metric conversion.
