Kind of weird. Maybe they just got the specs from a wrong page. They are selling it directly from their website for $399. Then they also have a listing on ebay where there is a BIN of $399 or BO + $14 shipping. Datavis seems legit. Just unsure how they ended up posting tri-band. I called earlier and the guy I spoke with also said tri-band.
Could there be an unofficial N73? Graymarket?
