If you have 200 trees to do, I would get a 200, new, or even a 201, you will not know the difference, I doubt you are a saw dork like most of us, so for that matter any of the real pro trim saws will serve your purpose.
Do yourself a favor and get used to that saw from the ground, take care to always use the brake when moving in the tree, wear proper PPE, and take your time. If you have never run a top handle in a tree, understand that that little light weight saw will mess you up in a flash because your going to be very tired in short order and it will bounce just as fast and hard as a big saw when you reach out to get the last little limb.
Might be a great........It would be a great idea to buy a small folding hand saw to do small limbs too, almost as fast as the power saw and better for the tree and your face when your tired.
