Depends on what you want it for. If I was going to be travelling, particuarly by air, with my Yani tenor I'd have a proper flight case made up. Might cost a few hundred quid but it'd be worth it. For what I actually do, where the sax never goes anywhere any more challenging than the boot of my car, I'll stick with the Yanagisawa case (which is actually pretty nice). The strongest case I have is one which came with a B & M Champion tenor. The case is as tanklike as the sax. The down side is that with the sax in, it weighs over 11kg.
