Assume that the homak
other options in similar price range could be masterforce or HF if not a must for 72" topbox, masterforce nice boxes and 11% rebate at moment.
strictly toolboxes dot com have a good range but top and bottom 72" will cost twice the northern tools homak you seen .
Box I quite liked recently at the price was the international tech series, do 56" and with shelf side locker would be around 71" .
If home use and must be 72" then homak would do, if more pro use then elite from strictly toolboxes would be way more durable.
Lot of good and not expensive 56" box sets but not many 72" sets as most just bottom cabinets at 72"
