My son would LOVE your display cabinet.. We picked up a smaller one, just like yours, but with two shelves in it, from a garage sale. The dudes were going to smash it with a sledge if we didn't buy it. They told me that after I paid them $25 for it.

My son is constantly switching out his most valuable comics/toys in it, and is begging for me to move it into his room. Right now, it's staying put in the garage, and weights a ton.. I really like your setup there.. Keep posting..
