Let me know via PM if you need someone to fix that for you. I know a great shop in southern Indiana.
Before it broke, how did that 2100 compare to your 390?
I bet your thinking of the same shop that I just got off the phone with. They are going to send me the parts and then I get the fun of putting it back together.
Its hard to compare the 2 saws the 390xp is like a sports car and the 2100 is more like a truck. If I had to choose one then it would be the 390xp.
