Been wanting to construct a small cabinet to lug to shows for sales pieces or maybe displaying one day. Cabinet inside dimensions are about 22" wide x 28" high by about 13" deep total. Cabinet was free, glass shelves were $125, electric guts (cord, boxes, switch, sockets, ballasts, bulbs) $100, sign white acrylic diffuser was $30. I got lucky with the acrylic and found a shop with a small left over piece and didn't have to pay for a full sheet. So about $255 total and it should hold 40-50 insulators. Not the fanciest cabinet but very utilitarian for taking to shows and traveling.
