Lego Star Wars #6206 Tie Fighter Interceptor, complete with figure and instruction manual. This is my son's very first Lego Star Wars set and he was so happy to see it. The thing is big and looks cool. He's been playing with it nonstop since I gave it to him. The set goes for around $60 on Ebay... got it for 1/10th of that.
Next was a Lego Pirates Loot Island #6421. While its missing some small pieces it is a very cool set with three figures, island, boat and more. This set I got for less then the price of a bag of chips!
Needless to say I will be hunting Ebay for more cool Lego sets.
