Bill, I was hoping to avoid a device that was dependent on line voltage (rather than zero crossings) for timing as it will then be line voltage sensitive (or at least more than a zero crossing detector). Of course zero voltage (zero crossing) detectors have other problems. Susceptibility to line noise being one major one.
