Finally pulled the trigger on a 360. Dell is selling the Pro at $200 with free shipping, so I couldn't resist. Amazon is also running a special where you get a $40 credit toward a future game purchase if you buy $80 worth of select games from them. So I picked up Marvel Ultimate Alliance 2, complete Lego Star Wars (figured my daughter would enjoy this), and Fight Night Round 3.
I bought a Pro when they lowered the price to $249 to clear the 60gb model out. I purchased it at Target and got a free wireless controller to go with it. My boy was happy to finally play Halo 3. Had a lot of fun playing coop with him. Now we are playing Hal0 3:ODST. I also bought Lego Star Wars, both kids are playing it coop.
