Good success with alternative valves?

In searching for replacement aquarium valves for my homemade non-balloon device I found a brass quick release on Amazon after no success at local shops. " Brass Double Shut-Off Quick Connect Tube Fitting, Barbed Coupler, 3/16" Tube ID, with Buna-N Seal " copy and paste that into the search for that site. It's just over $16, but with no slow leaks or forseeable quick need for replacement, I'm thrilled.

Damn nice valve. But $16! Wow.

One suitable check valve is what is used for radio control aircraft, for diesel or glow engines, available for $7-10. Some models can be disassembled for cleaning. Check your local hobby store.
