Gym Equipment Home

I want something for home use and want to know which piece of equipment to provide the best exercise for all the senses - the rowing machine or bike, or anything else? It should not be too large, and is available in more than 200 pounds, thanks! FYI - not that I need to lose weight, just want to be able to do some cardio at home - which is where I spend most of my time! I have fitness DVD now, but want a piece of equipment too! Get an exercise DVD - fits in a small space and use your own body weight for resistance. Try beach body - it works for me. (The draw back is the video Debbie horrible English grammar. For example, "* acrosst weapons your body.") I love you
