Also check out prices at McMasterCarr, the 'high flow' ones are the same style as the morebeer stainless QD's. I personally would avoid the CPC ones, they clog and I had problems with the o-rings breaking all the time. I would love to go the triclamp route, but way more pricey, but probably worth it if you're brewing all the time. And while making beer, if the brass ones are significantly cheaper, I would say go that route. The limited exposure to wort won't be enough to leach lead out.
I went the morebeer SS QD route, love 'em. But, I spent a gawdawful amount of money on them. If I were to do it again, I'd go brass.
Cheaper. Less shiny though.
