Does anybody know where can i buy something like a Korg Pad Kontrol or Akai LPD8 in BKK? May be somebody sell it used?

I have just been looking around Bangkok for a drum machine etc. in the end it was cheaper and easier to order online and import, I did the same with my headphones (sennheasier hd8). Good luck finding a shop (post details if you find a good one) but most shops seem to cater to either bands or digital djs (controllers for tractor/serato not mpc).
