Aloha! I prefer metal cabinets. True, they don't have that "earthy" appeal as wood does but it works. All museums have switch to metal over the years because of the affects of Byne's Disease. And my cabinets are all Sears Craftman tool cabinets. Had them for +20yrs now & no problems. When Tucker was still alive he recommended Craftsman steel cabinets because the steel gauge used was very thick & the over-all cost was very affordable. One turn of the key locks everything & i stack them since most are modulated in nature. I've seen metal map cabinets that are well made & are ideal storage lockers. Vidmar seems to be the prefered choice. But i still prefer Craftsman brand. And the black "foam-like" drawer liners that Sears sells will not break down or tarnish the shells they contact. Also when stacking use a rubber mat between units. Craftsman sells a mat just for this that works wonders. Mahalo!
