I guess the standard of pumps for the home brewer is the March. My LHBS doesn't have them... but they do have a pump made by Dayton (WW Grainger). Has anyone here used one? Be neat to know if someone has done either a side by side or a longevity test.
Unfortunately, I don't remember what the Dayton number is. All I know is it's white. Guess it boils down to black or white..
