Very nice looking takn, good output ranges. Also its very easy to change the output pressure, you just turn the big knob on the tank.
Can get dirty easily and if you do have a low low pressure gun, like under 200 then you need a different spring.
I like the the system, its probably one of the best nitro systems you can buy. My one quam with it is that its way to expensive. You could buy the nitro duck adjustable and that would work pretty good. If you've got the cash to burn then go for it because its got probably the best after market reg out there!
If you have a chance to buy it for a good deal on ebay or something then go for it. Otherwise its probably not worth 400 dollars. I bought mine for 200.
