I am in the market for a new blower and was pretty much decided on Redmax when my dealer suggested I take a look at the Maruyama. His spec sheet showed the Maruyama had a 700cfm and a maximum air speed at the end of the tube at 220mph. He only had 1 unit on the shelf and would not gas it up so I could see the power for myself because he said if he fueled it up he would have to sell the unit as a demo. Has anyone used this unit , and if so how does it compare to the Redmax 7000? I know the Echo pb650 is also very powerful, but I prefer to stay away from Echo because my pb603 has had problems with durabilaty. Any input would be appreciated.
