Irish,
As far as looking for one Cathe "program" you might be looking at it the wrong way. It may be easier to tell us how much money you'd like to spend and exactly what you're looking for whether it be weights, cardio, how many days you want to workout, what equipment you currently have. Even though there are series like "Body Blast Series" or "Intensity Series" these aren't really "programs" in the strict sense of the word, they are merely groups of workouts Cathe put out at the same time. That being said, with the weight training dvds I do find those to be more beneficial if done together, ie. doing the 3 Gym Style weight training workouts as a "package". Hope that makes some sense! Picking a Cathe dvd can be daunting!
I have the Timesaver dvd just b/c I felt like I "had" to have it, however since I have all the other dvds that comprise the Body Blast Series too, I dont do the TImesaver that often. It does have some extra footage for the weight segments so I think getting it if you dont already own the 3 dvds in the Body Blast series is worthwhile, but for me I dont reach for it too often.
Happy Shopping!
