I've used MTurk for a very subjective task: "Value the object in the image" for which I paid $0.10 per valuation (a maximum of 30 seconds was spend on the task). The valuations were fair but the workers of Mechanical Turk may have a different view of how much something "home made" or "retro" may be worth (typically far lower than the object would be worth for someone in the market for said object).
