Just my experience with my CO2 set up I have right now................. I liked that it was fairly cheap initially. You can just buy a beverage CO2 tank, a regulator, a hose and a fire extinguisher bracket and you have essentially the same set up as other "store bought" CO2 systems for less that half the cost.
I have a fancy adjustable regulator. I set it at 130 psi and haven't ever adjusted it yet. Also it has two gauges, kinda pointless because its always left at 130 psi and the tank pressure gauge doesn't give you an indication of tank level. The only way to tell how much is left in the tank is to weigh it. So all the features of the fancy regulator don't really matter to me.
Its light and simple. No fuses, wires, solenoids, PRV's, A/c style clutch and other things to go wrong. I sometimes use it as a shielding gas for my welder when my 75/25 runs out on the weekends.......and you can use it with a beer keg:sombrero:
Having the tanks filled is a major annoyance, just another thing you have to run out and do while your getting ready for your trip. Also everybody always wants to use it to air up back after a trip, making the gas go faster and the trips to fill it come more often. People always ask if they can borrow it.......lent it out once and it came back all scratched up
The portability between vehicles is nice, mine has been in three rigs now.
All in all I like the set up but if I were to do it all over again i think I would go with a York pump based system. The benifits of unlimited air without annoying refills beckons to me:drool:
