Play-Asia is selling GameCubes for just USD 39.0 (around RM 140) each. Available in a variety of colours (Jet Black, Spice Orange, Indigo, and Platinum) and with a free game included, I w ould say that this is a bargain. Check it out over here.
Since these are NTSC-J consoles, you’ll need Freeloader to run games from other regions.
