I am using Keter Masterloader Resin Rolling Tool Box. It is pretty good. It has pros like:-
It comes with removable dividers
Made from good quality chemical polypropylene resin making it a durable one
Manufactured from the good quality frame it makes the box hold heavy items
It does not have storage issues also. By the way u can check other options also
