That is the issue with homemade storage. With Lista/Vidmar ( or equivalent size ) draws you get at least 5x the storage per draw, with no lids to open. I have (5) 60" Vidmars, filled, I can go through all the drawers in all (5) in approx. < 3 minutes. That is equivalent to (5) cabinets times 12 drawers=60 drawers times (5) of the plastic cases= all the drawers together are the equivalent of 300 plastic cases.
How many plastic/metal cases can one pull out, open, then close in 3 minutes ? … not many.
As to cost for quality cabinets, I purchased Vidmar seconds for under $500 each, if your patient/diligent you can get used cabinets fairly cheap. I consider my Vidmars as one of the best shop/home purchases .
