For $125 last fall I got a 12' Wilderness Systems kayak in like new condition which is a total super steal of a deal. All it basically needs is some Armor All Original protectant once the weather warms up.
Ditto this for donating old but still working used lawn mowers and snowblowers.
Last June someone from Squam Lake donated a 23' pontoon boat with a 90-hp Honda and no trailer that was about twenty years old, and it got sold in about one week for something like $6500. It was in very nice shape and must have been stored and serviced at a marina.
