I want to mount my flash (Canon 430EX-II) on my tripod and I'd appreciate any advice on which flash shoe -- I think that's the proper term -- to get. Put differently, I want an adapter with a hot shoe and a standard tripod screw thread. There are many out there but most are cheap and get poor reviews for either braking or not securing the flash. Not even the Manfrotto-branded one seems any good. Ideally I'd want one that I can "lock", using the flash's locking mechanism. Many thanks in advance.
