I got lucky & found this LEGO set for sale already, had to jump on the review for all of the fans out there!
The set comes with 248 pieces, Mk. 43 Iron Man, Ultron Prime, Scarlet Witch, and The Hulk and is based on the events of the upcoming Avengers: Age of Ultron movie. I usually focus more on LEGO City and unlicensed lines, but the minifig selection and Hulkbuster mech build (which holds the Stark figure fully inside of it) struck me as a great package for a modest-sized set that won't break the bank. Leave a comment if you have any thoughts about it, yourself!
