I just bought one of these: for $109 and it is all but amazing. I've been using it on my KM110r and it has been doing great this past week. It has easily increased productivity 3:1 over my BG86. It is almost over kill for residentials and so much lighter (feeling) than a back pack blower. I'll pick up a km 130 in the next few weeks and that is going to make me even happier.
