Are you much of a comic book person at all?

Mattel's Dc Universe line, which recently ended, has a pretty wide selection of 6" DC Comics characters.

DC Collectibles (formerly DC Direct) is currently making 6.75" figures based on designs from DC's comic book reboot, the New 52. Their stuff has a reputation for being fragile, though, which I can definitely attest to. Their 3.75" toys aren't worth buying at all, they're both over-priced and highly likely to break.

On the Marvel side, Toybiz started the 6" Marvel Legends which have since been taken over and revived by Hasbro. There is also a pretty good selection of characters there, and the Toybiz stuff pretty regularly included diorama bases or highly detailed display stands.

Similar to DC Collectibles, Marvel Select has done a lot of 7" Marvel characters, including a few from the movies.

You also can't really go wrong with Hasbro's Marvel Universe 3.75" toys, which was rebranded under a new name recently though it escapes me at the moment. There is a pretty wide selection of characters to choose from.

For video game collectibles, Play Arts Kai seems the way to go - although there have also been numerous complaints about them regarding quality and durability.
