Elliptical Machines

I have tried all kinds of exercise equipment in the past. I have owned exercise bikes and treadmills, but have never used them for more than a month or two. A friend of mine had an elliptical machine, and I tried to use it. This was before my surgery, when I was vary top heavy, and I fell forward, and was stuck on the machine, parallel to the floor. My friend was laughing so hard it took her a couple of minutes to help me get off of it. Now that I am no longer as busty, I want to try it again. I was reading consumer reviews of elliptical machines and realized their are so many options out there. I am now on a mission to find one I can use easily.
