Reply to MIDI Keyboard & Controllers Hong Kong

I'm based in Hong Kong and I've decided to start delving into music production. I bought my DJ setup from local dealers (CDJ-1000's, DJM-800, Ikey monitors and MOTU Ultralite) but no luck with MIDI gear . So I'm hunting for a store that sells MIDI keyboards & controllers. Second hand gear is also good.

Must be some gear heads from HK who can help out!
