I don't know anything about the 1100 but I can tell you that the 500e is a fantastic machine. I wouldn't trade it for anything. But unless it's just recently came out, I don't think there's a case for the 500. A case would have to be really, really deep in width to fit this machine. When I bought my 500e last year my dealer couldn't find a case that it would fit into.
