I'm unsure if offering a racquet for sale in this forum is against the rules, but I currently have a Prince Air Vanquish OS grip 4 1/2 for sale on ebay. It is slightly used (only one month old). If you are looking for a used racquet that is in great shape, please take a look. You won't be disappointed.
