Nintendo products are really the most expensive and their prices never go down that easily:
1- Game Boy Advance SP Console: 350 and it's original games are around 140 - 200 Q.R
2- Nintendo DS: 600 - 650 for the console and the games around 140 - 200.
3- Nintendo Wii: 1700 - 1800 for the console and 220 - 275 for the games. You will find the one in virgin coming as a PAL system, while the ones that you will get from other shops NTSC system. Most of the games here are NTSC and you will find PAL only in virgin which are too less compared with the others. I got my Nintendo Wii from a friend who wanted to sell it and that was a very nice deal:
1- Nintendo Wii Console.
2- 2 Nintendo Wii Wireless Controllers.
3- 2 Nintendo Game Cube Wireless Controllers.
4- 7 Nintendo Wii Games.
5- 9 Nintendo Game Cube Games.
6- Memory Card for Game Cube.
7- 3 Controllers for the Game Cube wireless controllers.

Guess for how much was that? :)
