Bailey should be good, I don't like them myself as hear of too many failures.
Any diaphragem type is going to be louder than piston in general.
Mine is VERY loud, I even drilled the holes out as big as I dare without it collapsing, and it got a bit louder still!!
Pistons types tend to be more of a whistle, where as diaphragm ones tend to be more ssshhh sound, which I prefer.
I have a recirc one as well, and two switches for them so I can turn either one on or both or both off for chatter.
