I have had this machine for less 9 months and only used it about 25 times. I have never used the crank as it was used with a wise 2086. It is the newest version purchased from Tennis Warehouse. I am asking $1100 shipped or $1400 with the wise head. The wise head is about a year old with about 50 rackets strung. I have many references here on the forums. You can contact me on here, via email at email@example.com.
