I'm going to get a blower soon a backpack blower and am wondering if redmax is still a good blower to get. I hear a lot about getting shocked and really don't want to deal with that. I was considering echo and stihl also. What advantages do those two have and disadvantages? I was looking at echo because I have used a pb 403 before and it worked good. No problems at all. I want to spend 300-400. What blower is for me?
