Ok so I used a bushing to drop to 1/2" 
Then threaded in a 1/2 to 1/4" quick connect 
 
Now all I need is the valve... 
I have a JG ball valve, but from all the input here, looks like what I need is a needle valve. 
 
Now I've sourced out some, but all from the US. And these things aren't cheap! 
$20-25USD +shipping... 
 
Any ideas for a local source? 
I'll call Sheret tomorrow.
