based on the info last saturday 15 June 2013. I went in 3 different shop which located next to another near AJ.
1. AJ RM 550 = with string and grip - but if its ultimax and other high end add in RM 5
2. Perfect Sports = RM 500 + with string and grip. Go look for Mr Wai. He is very helpful and accomodating (this shop located near to AJ)
3. The shop in the middle (I forgot the shop name) sell it for RM 520 if i am not mistaken.
actually this 3 shop is having a price competition somehow. AJ which is the long established shop at that place vs the emergence individual (the shop in between AJ and Perfect sports) vs the Perfects sport (which i know the branch of Racquet World of Pertama complex).
based on my observation and recommendation for the Zforce. U could go to Perfect Sport which sold cheaper ( I heard they can give 40% discount on old model racquet due to lower price quoted by the distributer based on volume they ordered from Sunrise. Among other which i know enjoy this special privilleges is the Hock Eng Bangi. As for AJ i m not sure though.)
And for the string alone from these 3 shop. i notice the shop in between the AJ and the Perfect Sport (I am sorry i forgot the shop name) sell very cheap. For instance Nanogy 98 is sold around RM 33. For comparison AJ is selling at RM 40, Perfect Sport RM 35 and Hock Eng Bangi RM 39.
As for the shoes....Its hard to tell. basically Perfect Sport can give u RM 10 lower than the competitor. Eg. Asics Gel Rocket New color AJ = RM 199, Hock Eng Bangi RM 199, Racquet World = RM 199, Perfect Sports = RM 190 (maybe because I nego kaw kaw)
As for those shop owner who frequently visited this page. I am sorry to reveal those. As i wanted all the BC members to get benefit of lower price.

I love to survey around. and get the best bargain of all those
