Any suggestions? I would be willing to spend a bit more if it is worth it. The treadmill is just too hard on my legs and I get shin splints. Besides, I heard you get a better workout using an elliptical. Anyway, I was looking at this one. http://www.sportsauthority.com/product/index.jsp?productId=2909658&clickid=body_rv_img How does that one look? Free shipping is nice but that price seems low. I don't want to buy a total piece of shit. http://www.sportsauthority.com/product/index.jsp?productId=2934848&clickid=body_rv_img This one is obviously better but is it worth the price difference? I pretty much don't know anything about the equipment so I am opens to any suggestions from more seasoned fitness people. Thanks.
