I have a beckett injector and high quality housing w/quick disconnect Banjo fitting that was going to be used on an Austin Oceans/Barr Aquatics Foaminator skimmer but plans changed. It matches up perfectly with their skimmer bodies but would also make a great unit for a DIY'er.
Here is more info on the unit, but mine includes a Banjo quick disconnect:
