I, too, use the Plano tackle boxes, only because I really didn't have a better way to store them. It's been 20+ years now so I guess I'm happy with them.
I am building a new router table, though, and want to keep my most commonly used bits right at hand. I bought a couple packs of the Rockler inserts and will be using them. Remains to be seen how I like them.
I have always had bad luck with drilling holes in wood. Either the wood shrinks and swells, sticking the bit; or I get rust. NO thanks.
