Egofit treadmill, used only a few months. I paid $600 for it, asking $300 OBO. Works great, VERY quiet, variable speeds, comes with a supply of silicone lubricant. Only getting rid of it due to a personal injury. It weighs about 50 pounds, but has wheels on one end. Dimensions are: Length 38 inches, Width 21 inches, Height 6.5 inches. Can fit easily under a desk.
