I just bought (waiting for it to show in the mail) the P90X3 (which is also an intense workout based on 30 minutes).
I chose P90X3 over T25 because I completed 1/2 of the insanity with Shaun T and was ok but I wanted a different trainer since Tony Horton talks a bit less and he's older so I think I will like it better...

About getting a copy you should buy but if you want to kick the tires you can get it from a torrent, all of them exists on the web, just get some it geeky friend to help you get them if you don't know.
Note: My pirated insanity training did not work half way so I quit. I handsight I should've bought it, that's why I bought P90X3
