I just have the 3120 Muffler Pipe saw left that runs on Gas. The 026 last I heard lives on its own mat next to a computer and gets washed daily as it gets worked hard all day in the woods...
I have seen it run and it does very good. The 3120KD is for someone just getting started into racing that doesn't want to spend 2k+ on a saw to learn on. You half to learn to stand before you can walk.
