Take note that Kin-Yee and Lung Tang include free stringing service, you can choose whatever you want. Kin-Yees stringer (slim guy with glasses) is top-notch on his red VE-80. Official Victor stringer for Korea Open, Hong Kong Open and Macau Open. Lung Tang gave me 100 HKD discount for unstrung rackets instore. I would ask if 900HKD is include or exclude strings and service because I made the experience that the prices in HK are every equal in terms of racquets. Regardless if Kin-Yee, Luxis, E78 or Lung Tang.
