I'm having one made by another master in this business, David Spiegelthal. I use one of his with my Alto and couldn't be happier. A third - tempting - possibility would be a Behn Ouverture. Heck, 50-odd dollars, and his soprano beaks are really good.
So, no more excuses, now I have to repad that monster and get rid of the noise and of metal clacking against metal (some cautious straightening is on order).
