My purchase of a 580 has all but eliminated my use of a wheel blower. I originally was considering the Shindaiwa EB802 because I have gotten such great service out of my EB630s, but the exhaust on it seems to make it much less of a blower than it should be. For me it came down to the Shin 802, Echo 770 and Husky 580 and the 580 untimately won.
Here's a short video I made of the 580 in action...should have put some bigger firewood out. http://www.youtube.com/watch?v=RgxwaIoSuhg
