Not sure I understand why anyone would buy a used sleeping bag or tent. Kind of like buying a used mattress - too many body soil/deterioration concerns. If money is an issue, buy a (new) import - ones that are a reasonable compromise of price and weight are available through Campmor. On the other hand, if you find a $500 nearly new sleeping bag or tent for a deep discount, maybe that makes sense, although I would guess that most folks who buy high end stuff like that use it a lot, so most items will be well used. Wouldn't want to buy it sight unseen.
