I see prices range from $28 at midwest up to $50+ all say 12" 304 stainless and are domed with a 3/8" brass barb...any difference? any recommendations? Any to stay away from? Also, I put a DIY spigot on the cooler with a 1/2 barb inside...Is that going to be a problem connecting to the 3/8" or stretch a 3/8 ID hose over it? The way I tightened it will be a PITA to remove...
