thye are still hard to find i got mine about this time last year for xmas, i used the wii tracker as well, just be ready to buy as soon as you get notified they sell out quick....
good luck.
and dont fall for the bundle deals, you fdont save any money just get the system, then buy the "play" game that comes with a wiimote, then try to find used wiimotes to save a few bucks....
we've had our about a year and it still gets used all the time, although this weekend my 7 year old discovered scummVM on our xbox, its been impossible to tear him away from sam n max.....
