I called Gilmour directly and ordered the 75QGFMR. It wasn't any cheaper by ordering direct, $67.59 plus shipping ($6.00 to SC). I opted for the 75 (Foamaster) unit as opposed to the 95 series (Foamaster II). I like the brass fittings rather than plastic on the 95. That's the main difference as was explained to me. Apparently bleach kills brass, so for those where bleach is used, the Foamaster will fail :-(
I have seen similar units online on some of the autocare sites, but I felt better knowing exactly what I was getting by ordering from them directly. I know PakShak has the same unit but I'm sure shipping from Hawaii to the East Coast would have killed it.
