p90x 2 or other strength workouts

My brother gave me the first 7 workouts for p90x, he said he would give me the rest when I was ready, now he says i have to buy it, the whole thing, so im quite irritated, Im not going to buy p90x since I have half of it already, but I need some new workouts, I only use p90x for the strength parts (chest and back, shoulders and arms, legs and back, and occationaly kempo x) then I run for my cardio, so should I maybe buy p90x 2 even though I dont use the whole system, or what else might be a good at home strength workout to invest in.
