Even Ultron Mark I is expensive to me at $250. Makes sense though, it's a very intricate figure. I doubt the drones will be any cheaper than that.
If they are $250 as well I might just get 4 and not 6, and that would be spread out over a year or so, if they are still in stock......... and don't even talk to me about the Iron Legion drones
