Today I replaced the stands with this one: http://www.prospekthalter.com/Warent...e-12-7-cm.html
Ordered them yesterday and got them today. They were made for collector plates, but can be used for steelbooks as well. I like them!
Thats a great idea, when you have the time can you take a photo of a steelbook with that display stand? It'll be great to see what it looks like with a game before I buy
