a quick search reveled this, although it was from 2008 for 500$ - you might want to search some more - I don't think there are any mass market cameras, but enthusiast cameras should available somewhere:

regarding 360 Stereoscopic panoramas - if you are looking for a simple way then I doubt that's feasible
The problem lies with the core notion of such a camera- it's a sphere - that is - one point - as opposed to 2 viewpoints required for stereoscopic vision - having 2 panoramic cameras wouldn't solve the issue either as the 3d would be properly viewed only from one point
the other, doable but cumbersome solution is having a regular stereoscopic camera and stitching together the 3d images like so:

this is what panoramic cameras (at least some of them) look like:
technically, a camera could be made with stereoscopic 3d in mind where each camera is actually a set of cameras like so:
indeed, you could hardwire some Fuji W3's or Minoru3D's for this task
Minoru 3D Webcam has a 42° FOV
The W3 has a low Fov BUT you could use Fuji W3's with Auxuilliary lense adapters which will give you a wide FOV like so:
you could In theory construct something akin to this:
there will of course be technical difficulties in synchronizing all those W3's, and since their battery live's aren't great you'll need power adapters:
also, if you are on a budget you might want to go with a single row of Fuji W3's to get started, as that might provide a good result as is.
if your scene is not in motion you can use a traditional 3d camera for shoot-> rotate a bit on tripod-> shoot then stich em all up:
