Just get stuff you like. A lot of stuff floating around on e-bay.
Of course I'll get things I like but I'm also looking for cool things you can find easily. I'm not much of an online shopper that's why.
Like where would you find the TOS minimates? Those are tight!
Entertainment Earth has a large selection online. I'm not sure about where to find them locally unless you try a comic book specialty store near where you live. I know that I have seen them at my local comic shops here in Indianapolis, IN.
