I would like to get a Yonex armortec 900 Technique in Malaysia but i'm unsure which seller i should go to :S
Maybe you should try your luck here : http://www.badmintoncentral.com/forums/showthread.php/54449-BEST-YONEX-PRICE-in-Malaysia
if u r in Sabah, u can try Giza sport at KK.. it offers variety of yonex racket with good discount too
bsc serdang pro shop. SOMETIME this shop sell below 'market' price for ip coded racket. other than that, #4 will guide u well.
