i like those hanson ones too. i like them standing up too. i have one mechanic's time saver magnetic one for shallow 3/8 if i need a carry around one 1" down to 1/4"- that one is good for 75% stuff outside of the shop. then i have the hanson ones for sae and metric, deep and shallow, thin wall and impact. the only drawback on the hanson is you need a pretty deep drawer for the 1/2" ones. you could trim off the plastic centers preempivly so they wouldn't break if thats a concern.
