I just bought a BR 600 man what a diffrence from a smaller blower. The only two down falls are the gas cap and the gas filter positionig. When the machine is half full of gas it doesnt run as good as when it is full. Overall I think it is a great blower.
Let me know if you might be interested in shooting a video review of this. We are about to put up a large site that will have user submitted reviews of all sorts of lawn equipment.
