I need some suggestions please. I only build aircraft in 1/48 scale. The planes are displayed in my basement on wooden shelves mounted on the walls of the basement. My collection of built aircraft is exceeding 200+. I used to be able to keep up dusting off the planes. But my collection is growing so large so that I cannot keep up with the dusting off. I need to display my models better than having them on wooden shelves exposed to getting dusty. I looked on line and I cannot find any good clear acrylic floor model display cases. I do not want to spend a arm and a leg(no more that $500/case). I also cannot find any large enough for 1/48 scale bombers(these plane can take up a lot of space). I now I could scale down to 1/72nd. I prefer 1/48th scale. Any ideas?
