As a reader found, Harbor Freight Tools offers the Haul Master 2,000-lb. Capacity Truck Bed Unloader for $39.99 plus $6.99 for shipping. That's the lowest total price we could find by $54. (For further comparison, it's also $43 less than a similar 2,200-lb. capacity truck unloader we saw three days ago.) It's compatible with 1/2 ton, compact, and step-side pickup truck beds.
