I guess it depends on your definition of portable. When travelling I just use a simple whip with a guage on it....mind you, some of you guys love your shiny boxes

I can't see a case for seperate inputs and seperate valves if it's not all plumbed in. Without that a 'panel' rather vanishes.
I used to throw a couple of Js in
the car plus the haskel but these days I've discovered I can do a week's diving whip filling from a pair of 7Ls so I can't be bothered to blend on the fly.
