I have red max 8000 (2) kawa (2) each are backpacks. I have one little wonder 11 hp blower that is awesome. Still didn;t have the blowing machines to cover last years fall season and looking at something this season. Spend $600 for another Red max or get another walk behind blower? Then if I get a walk behind - should I get something different than our little wonder? Any other brands that you guys think is better or less problems?
