I need your opinions please

I have been told by several people to get a AB Lounge--they all swear by it--also an elliptical was recommended as well and I remember enjoying that at the gym a few years ago--does anyone have either of these? and do you recommend them? Im using my treadmill and swimming in the pool daily but would like something else to do....

Do you personally want to own one of those or could you just join a gym and use it at a cheaper rate? I know I use all the machines I can at the school gym, and when I'm in better shape, watch out stair master and bikes! hehehe I am also planning to start swimming but don't have a suit... yet
