LOVE THEM!!!!
i have Mark I, II (custom painted silver like the movie), III, prototype/tony, opening cockpit iron monger, war machine, spare Mark II for a desert ops custom i'm gonna do someday) and just last week i nabbed a captain america iron man!
he's pretty good but the colors seem kinda funky. blue is a little light, and the silver paint apps on his biceps is too thin. i can fix that easy but beware when you pick yours up.
btw if you dont know, this is actually steve rogers, captain america in a suit of armor (actually a gift from tony to steve) from the comic What if? Civil War. here is the cover...

its a great read if you enjoyed the civil war event.
