I personally think buying new with the CTL is a smart move unless you find a killer deal. Excavators on the other hand just do not wear near as much per hour so getting one used is no big deal. My KX161 is nearing 2000 hours and I am amazed at how the machine has almost no wear. The tracks still look new.
My CTL with 1200 hours looks like it was rolled down a cliff.LOL
