Fun saws for sure.
Had you let me know I would have been happy to drop my 201 rear handle in the box with the 661.
As luck would have it I shipped it out this week .
I was looking for the same for my son. I bought a husky 125 battery and he runs it well. I also picked up a almost new used Makita 4300. Both together were less than a used 201 rear handle I sold to my BIL.
