I have the KM-90R with the pole pruner attachment (among others). It's the smallest of Stihl's professional Kombi units, but it has not disappointed me yet. I haven't compared it to its larger brothers, but I can tell you that it keeps its speed when buried.
Why the KM-90R? I had an immediate need for a Kombi with the articulating hedge trimmer attachment and my dealer didn't have the 110R or 130R in stock that day, LOL.
