Dynafit Radical ST. You can get em with 130mm brakes, they're cheaper than the FTs and don't have the pointless 'flex plate' so they're lighter too. You probably don't need the release values to go up to 12.
They're not much fun on hard, refrozen pistes, but you won't be taking Megawatts out on those anyway, right? Unless most of your skiing involves mechanical uplift of some kind, there aren't many reasons to get any other sort of binding.
There's no reason not to trust the release values even in the absense of DIN certification; you can get a dynafit setup torque tested by a suitable equipped ski tech to see that it is entirely comparable to frame bindings. The major problem is that the setup is very sensitive to misaligned bindings or slightly-out-of-spec boot fittings. Well worth getting the bindings professionally mounted for that reason.
