I have/had a GG Foam Gun - ya know the one that goes on the end of the garden hose. This is the second or third unit as none of them lasted - that aside GG Customer Service is excellent.

So, I`m thinking about either getting one but am also considering getting a PW and if I get the PW would get the foam cannon. Would this be a wasteful redundancy in equipment and technique having both the foam gun and cannon?
