If you were going to buy a new 360 where would you buy one?  Which store do you think would be most likely to have the latest model of the motherboard or the arcade model with the extra memory?  Is there a way to tell if your console is a jasper before you ever leave the store?  This is mainly for USA residents as I live in the USA.

I always try to buy my consoles and games from outlets that deal only in games.  I'd rather support a gaming shop (like EB Games) over say... Walmart or Costco or any other large mega chain corporation.
