Yup have several sets of these.  Very nice.

Victory Force has great zombies in static poses.  I just cut off the bases.

Warlord Games: Carrion Regardless (celt casaulties) are an option. Though they're more injured that quite dead. Still, they are quite cheap (and that's what really matters).

I haven't gotten around to making them yet, but I bought a bunch of Heroclix in flying poses to make corpses (or surprise zombies).

They have outstretched arms, heads tipped back, and toes pointed.  Just flatten one side with a hobby knife and off you go.
