In my hunts last week I saw the Imaginext Dinosaurs Doc and Exo Suit set, which repaints the existing smaller "mech" suit and adds a small pterosaur to the mix. Unlike the picture, the sample I saw had the opening canopy section completely vac-metal-- not black and vac-metal silver, but totally silver with a couple of painted details. (It was scuffed, otherwise I'd have bought it.) It ships in the same case as the Ankylosaurus and Raptor sets. Good hunting! A lot of new items are showing up now, particularly at Kmart and Target due to their resets.
This set retails for about $10.99. Previously the Mech Suit has been sold in other colors and with other figures for $5.99-$6.99. Minus the dinosaur, obviously.
