Stores are sold out, and I don't need one untill Christmas, which is good. Do you think I should just grab the first one I find, or do you think they will be back in good supply before Christmas?

These are pretty popular toys, I would grab the first one you find.

Well, are you asking about the actual Legos that make SW scenes, or Legos Star Wars 2 Video game?

You could purchase the first one that you find and don't open the package & hold on to the receipt and purchase it again if you find it at a better price and return the first one that you bought. Some stores (Target, ToysRUs...) let you return things for 90 days.

Honestly, I don't think you're going to find it for less then 39.99(for the PS2, GC, and Xbox versions) for quite awhile(untill it hits the platinum hits stage). So, I'd buy the first one I saw.

And it is a very fun game. Challenging, but fun. I am personally at 85% complete right now.
