I think all of Loriano's new cases have been sold but Toddi may have some of his Acrylic Cases available still. While not as nice as Loriano's cases, they are much less expensive. I think it may be hard to find a used case unless someone's 1541U dies, but I hope you find what you want.
I bought an Acrylic Case for mine. It protects the board, which was my biggest concern. You have to glue it together with Superglue so it is easy to make a mess if you aren't careful. I only goofed up a small area of mine so it turned out OK.
I don't think he lurks here at all. I really don't know what the price is off hand and I'd hate to give you one without knowing for sure. It's not cheap, but it was worth it in the long run to protect the 1541U. I'm sure you'll get a reply from him with the cost once you send him a message.
