I needed to purchase a pulling sled from the good men down at Elite Fitness Systems. Unfortunitly the total cost (with shipping) comes to about $225US. I live in Canada so the real cost to me is about double that. I go to University and live away from home, so I cannot afford to spend that kind of money. Does anyone have any suggestions on how I could make my very own GPP metal Sled? I have access to a welder but no oxy-acetalyn torch.
