don't know if this helps, but I've made a few different purchases recently, from www.bargainfittings.com
, quick shipping (2 days in my case), $5.00 flat rate! I had looked around to put together individual pieces, but price wise, was just as good to buy their kits! there's also a few other vendors on this forum around the same, and i went weldless, and never had a single leak!! (teflon tape) Good luck, and Happy Brewing!!
