That's pretty slick, I like that fill yoke much better than the clamp I have that you have to turn the little knob real fast to vent. I have the S200 with the quick charge deal on the front of the cylinder, but no air gauge, did you make that quick fill yourself, or is it some other aftermarket goodie, does it come with the gauge? Would love to have a gauge on my S200, but I'm not quite ready to fork over $130 for a new cylinder and fill adapter.
Cool stuff!
