If you are looking to purchase something to use to work out on or with here is what I have:
I purchased an Air Climber ($99, I think I bought it on HSN or QVC, can't remember which one). There isn't much to it, it's basically a mini-stair climber. But, it works the daylights out of me. I am just beginning with working out and it is all I can do to get through the beginners workout. It really is fun too. The lady who does the workout video it came with is a bit on the annoying side, but if you just follow along and ingore her annoyance, you can take it.
For strength training I found a Fluidity Bar and workout videos ($199 before shipping, they let you pay in installments at fluidity.com). I love this workout!!!! I can't say enough about it. This is one I could do everyday, right now I do it three times a week and the Air Climber 4 times a week. It's not cardio, but it really works you without free weights (which I don't enjoy). It's pricey, but totally worth the money. I have been using it for about a month now, before adding Alli to my routine. When I first began the workouts I couldn't do most of the workouts, I was just so far out of shape. Now, I can get through them all and am following the Intermediate lady rather than the beginner lady. My goal is to get really good doing the Intermediate on the Begninner video then I will switch to the Intermediate Video. It comes with beginner, intermediate, and advanced. On each video there is a lady doing it as a beginner, a lady doing it as an intermediate, and a lady doing it as an advanced. So there is lots of variations within each video.
Anyway, having a mixtures keeps it lively! I think the trick is to find something that you enjoy so you will stick to it.
