I want to lose 30 Lbs to get back into shape. I am on Raw Paleo diet and go for a walk every day. Just looking at buying a new exercise equipment for my home gym, but can't decide between treadmill and elliptical trainer. I have used both equipments at our local gym and impressed with the results. Both are available at http://www.dealrocker.com with good discounts. Can anyone point me in the right direction and help me to choose the best one?

Any advice and recommendations are welcome.
