These models will do nicely for spirits or elementals, maybe in D&D or in Frostgrave. I picked them up for well under a pound each from Blue Rat Games. They're Solstice and Living Lightning originally, but I really wanted them because of their cool clear plastic. Pried them off their bases, stuck them on new ones, textured them and was done. Frugal as you like.
Clicky models tend to be on the large side, but they're very variable and I've never cared much. Still, even if you're picky about that kind of thing, you can still find a lot of cool models for use as monsters, robots and so on, even if the humans are a little on the big side.
