I got mine from BBTS.
Never seen them locally.
Oops. Just saw they list them as being 14 inches, not 18.
They're huge, anyway.
Done by Mezco, and they're very cheap for what they are. They're not super-articulated, but there's enough to give you some nice posing options.
There's also a SDCC Cheetara that came with Snarf, the regular one doesn't.
They use the classic designs too, not the most recent look.
