I have a 3 month old Wise electronic constant-pull 2086 tension head. It was purchased 11/28/2005 and installed on 12/15/2005. It is in almost new condition. I have strung just under 40 racquets on it. It still carries a warranty. This is the new version with the new style string gripper (great improvement). I will ship it in the original package with all cables and manual. Also included is the optional foot switch ($35 new). I am asking $475 including shipping with $500 insured UPS, U.S. only. I bought it less than four months ago for $555. This machine works great only reason I am selling is I am upgrading to a new machine. ********* Product is SOLD *********** Thanks TW for providing this service!
