Re: The Action Figure and Toy Collecting and Discussion Thread!
Best thing I can think of is Minimates. They're kinda close to Lego figures, but there's plenty of Star Trek ones. Thing is, though, they're intended for collectors, so they aren't necessarily cheap for what you get. They're the only Star Trek figures that size that I know of, though.
Try here and see if any catch your fancy
