Has anyone built their own?
I see it's just a pressure regulator with some tubing hooked to it. I'm guessing it couldn't cost more than $10 to build.
If so lets see some pictures and materials you used.
I'm the type of person that likes to build their own stuff from time to time. I don't mind paying the money for a "pre built" one, but if I can put a little sweat equity into it and it works, it'll sure feel good. A little sense of pride if you will...(Not trying to be a cheapazz by all means)
Also, if I'm offending any of the vendors that sell this product I won't mind if this thread gets deleted. (Don't want to cause any problems)
