We have two used Vibe traction units made by pro-flex. These units were used in a CLEAR technique clinic but now the Dr. is moving to a new city and has extra equipment. They were purchased for over $3,000 each and have been gently used. One of the units needs the vibrating head replaced which is approximately $300-400. The other unit is ready to go. We are asking $2200 for the working unit and $1600 for the one that needs the head replaced.
