I agree with Andreas that the plastic ones don't look
cheap. They're not what you'd think of though for a display case in my opinion.
The wooden ones look
cheap. Three pics below. You can see the wrping on one of the boxes. Every single one of them is a little warped.
You can also see that the stain is
cheap, put on thinly, that the sides of the drawer covers aren't finished real well and that the stain is starting to fade, and that the stain is not so much mahoghany as it is oompah loompah orange.
