I'm not sure you will find it as challenging as Bootcamp, but KPC is intense, and the premixes that combine it with Legs and Glutes are good as well.
HSTA is rather Bootcampy (as is HSC, but with a little less intensity), but they both use the High Step (for many sets of step-ups in HSTA, and cardio in both HSTA and HSC).
It sounds like maybe "Drill Max" from the upcoming series might be a possiblity as well.
