The "WheelEasy LE" is a folding wheelbarrow, replacing the heavy steel or plastic tubs of conventional haulers with a 3-cubic-foot, vinyl-coated nylon basin which can hold up to 150 pounds. You won't be carting around concrete or bears*, but when it comes to dirt or lawn clippings, the WheelEasy has one clear advantage over solid barrows: because it can lie completely flat on the ground, it's easy to quickly rake it full without shoveling stuff up over the side.
You can find them for around $35, says ToolMonger, but at retail they're more like $60.
