As the thread title implies I am wondering if anyone has any idea of some quick disconnect fittings that are usable in a loop with a proc block.

What I am looking for:
- Not too restrictive
- Not ridiculously expensive for a loop (around compression fitting prices)
- Look decent (Not as important)

I really love the idea of QDs but I have yet too find any that meet my requirements. If you know of any QDs that meet at least my first two requirements please recommend them. So far I have only seen the Colder plastic fittings and the Koolance ones mentioned for use in WCing.

Any thoughts?
