Nope. You don't need to have a prepackaged system at all. It'll take a 
little more running around to setup your own system but you might save money 
in doing it.

Yes and no. It will prevent dumping TO A CERTAIN EXTENT. If you look at the 
comparison chart for the regulators on the Aquabotanic site you'll notice 
that the 2 stage regulators have a smaller "outlet pressure rise" number. 
This means that 2 stage regulators will dump less but it WILL still dump.

I don't know about a needle valve preventing dumping. If you look at that 
geocities link I gave you and then click on the "low-pressure" link you'll 
see that Steve Dixon noticed a dump even w/ a metering valve. So I guess a 
dump is STILL possible w/ a metering/needle valve. Quite a few people using 
"low-pressure" systems have not seen this dump occur however. Either that or 
they just didn't speak up when that poll occured.

Hey, its the American way!

Hehehehe... something like that!
