And WHY do you "really want a chainsaw" so badly ?? Next thing we'll hear is that you want a wood chipper, too. 
Because I have trees in my yard that have branches I cannot saw off with a bowsaw. I have been told "Don't worry about it, so and so has a chainsaw, we will get him to come over and take care of it." That ain't happened. It really isn't enough to pay someone to do it, just a few dead branches here and there, and some shaping of some shrub/trees that have become a little unruly.
Essentially guys, I want a chainsaw so I can do the work myself, or have someone that knows how to operate a chainsaw, to come over and help me with it.
If I got a Food Processor, and a Kinect, and my trees still look the same come spring, I will still be bitching about wanting a chainsaw.
