Looking for a Basic Lego set with mostly large bricks I am looking to buy my son his first set of LEGO bricks (because my mom will not give me my old ones!!!). Most of the 650ish piece sets I have looked at contain a large amount of 1x2, 2x2, etc. I am looking for a set that has more 2x4s, 2x6s or bigger than those with more smaller pieces. Can anyone recommend a good set? It does not need to be that big of a set either, but if I could find one that would be great!! I cannot wait to finally own my own LEGO bricks that don't actually belong to my parents!!!
If you can get to a Lego shop, there is a Pick a Brick wall with mostly large bricks that you buy by the cupful for less per brick than you would pay in most sets.

These two sites:

, and

show you the current(ish) contents of the Pick a Brick walls around the world, they are updated by fans so they might not be up to date.
