I got a nice Wiikey with a hologram from them, it has not failed me since and successfully flashed to 1.9g so I assume it is genuine, but that was in November of last year.
Wow! Thanks for all the fast replies! This really helped me.
EDIT: Another quick question. To my knowledge after I solder the wiikey to the wii i then only have to use the 1.9g disk on it, the config disk (both with a Gamecube controller), and then burn a game disk and im all set?
