Has any one bought one of the new BR 600 Sthil BP blowers yet? The numbers are very impressive. I have the BR 420 and it has been awesome. Looking at getting a second BP blower and want one that has a little more force. I have heard allot of good things about the Redmax 7001 also, but it is allot older technology and the dealer told me to stay away from any of the new Strato Charged engines.
