I just used the "twist" valve.  Cheap and easy.  It outperforms my 
Ezi-Hang by far.  I can get twice the height from the spud gun.  Mine 
is made out of high strength pipe that is not UV stabilized but I 
figured that it wouldn't be spending that much time in the sun 
anyway.  I have 12 volt compressor and a small gel-cell battery and I 
pump it up to 100 psi and pop away it goes.  Best antenna investment 
I have made yet.  And my kids think it's the funniest thing going.

Shooting over 30m+ gum trees is a breeze.  Now all I have to worry 
about is the snakes when I am looking for the weight.
