MP-100 is 756 HKD at Mr Keen's Sports and Goods, Aberdeen, HK. I'm thinking of getting either an Iso Ti Swing Power ($700) or Ti-10 ($640) from there this Christmas =P Go here for the full street address: http://www.badmintonforum.com/vb/showthread.php?s=&threadid=8188 Good luck!
www.luxissportnet.com/intro.swf That's luxis's website. It's got loads of superior quality JP/CN rackets but they're well expensive. Dunno of any other sites though.
Puff, the MP 100 has been discontinued in the UK for about 6-7 months. I know where you can get an imported Indonesian one for £80 brand new but do not know if the store does mail order. If you want the details then PM me.
