i got one from them not to long ago (2 weeks maybe) and its description said it included everything (including the wii sports game) exept for the silicone covers for the wii-mote and the wrist strap, and it came with everything it said, so if it doesnt say it has everything, i wouldnt risk it.
edit: however my wii is in good shape and ive had no issues with it, checked dual layer disc's and gamecube games. no problems with anything so far
