I've seen a couple of these in my area for about $10. Who made them and what's the value of them? They seem like they'd be useful.
Edit: After a quick google image search I'm leaning toward the possibility that it may be custom made. However, I know that I've seen another one just like it at a local pawn shop. It didn't have any stickers or labeling on the top of it either. I'm sure someone can either confirm or reject the possibility of this being a 3rd party item.
