I use a Power Tank. I don't have Monster Valves. I simply remove the valve stems to air down and use the Power Tank to air up.
Although it isn't as crazy fast as in this video, a high speed valve stem tool complete with spare valve stems is about $5-6. Generally speaking, I've got all four tires aired up in about the time it takes others with on-board air to do one tire.
Edit: Yes, valve stem cores. That's what I meant to say. Again, very easy. Very effective. Very cheap.
Good idea to have spare cores just in case you shoot one into the woods.
I've been using the valve caps with the built in core remover forever and would not even use an airdown tool if i had it. What a gimmick. You do need to be carfull not to let the air rushing out blow the valve core out of your fingers but after a couple of times doing it this way it's really fast and simple. I just hold my guage up to the open valve and reinstall the core when i'm close to the PSI I need. Walmart has a 4 pack for about $1.00. http://www.amazon.com/Myers-Valve-Stem- ... B003LNOJUK
