I'm doing Tae-Bo bootcamp as well right now. I love the series and think it's a great workout. I'd walk as well but seeing as it's 20+ degrees outside, I might become a popsicle :P If it's nice where you live, walking is a great way to get started! Gets you moving and the blood circulating more than doing nothing
Ebay is a great place to buy your fitness stuff as RachelleS said. If you're looking to try the tae-bo bootcamp series, I would go to Walgreens. I saw it there for $40 (I paid close to $60 off of billyblanks.com but got an extra dvd along with it), you can also find different videotapes at dollar stores. I saw a tae-bo videotape at my local dollar store the other day, it was an older one, but they still do the trick!!
I agree with the others that say, just start doing what you can think of. You only burn 77 calories by doing nothing, imagine what you could burn by walking, or running up and down stairs
