I got mine from Electronic City in Olympic Square.
RMB
2300 - Console + 1 controller
300 - Mod-chip (installed)
500 - Extra controller ("real"

5-8 - games
You should be able to get it a little cheaper than I what I paid. I bought mine the day it came out.
They also have Gamecube games which can run on the Wii. You need to buy a controller and a memory card (I forget what I paid...not too much).
Good luck
