I would stay away, especially if you need to pay for it in full right now.
Around the time of the PS3 launch, there were many sites like this. Ultimately they were unable to deliver. Some of them were just total scams.
Nice looking site though.
I orderd from Rombie in Sept. I have been hearing about all the beware talk. I agree it sounds fishy. I have been checking my card and there has not been any purcheses. I emailed the sight and asked when they ship, i got a reply 11/15, which is the day my card will probably be charged. I'm taking a shot. I have their recipt and worse case is I file fraud with my credit card company and they will remove the charge and cancle card. Not a big deal. Better than standing in line at night hopping the store get enough in.. and dealing with holidays crowds.
