Yeah, CY, that looks like the stuff to buy. A guy at my WI gun club had some last summer and he said it was a blast, pyrotechinically and emotionally. Good stuff.
FWIW, the "bleeding zombie" targets on that same website are pretty good in terms of number of hits they'll sustain. They'll be a bit messy to take home if you haven't shot 'em to smithereenies, but that's nothing that a plastic tarp and a cardboard box won't take care of.
For those who want to make their own targets, take a look at this website:

I have used the plastic 3D male torso target ($65 retail) quite a lot in my training and it is DEFINITELY amenable to modification with stuff like bleeding paintballs and the like. Each torso target is good for 300-500 hits (with HP ammo, yet!) depending on how accurately you shoot.
