Product Idea

Skid Loader

What is it? : It's a sort of a small, rigid-frame, engine-powered work machine (a sort of a Bobcat).
Why did you build it?: I built for my son. 
And Why do you believe this would make a great LEGO set?: I Think this could be a good "little and cheaper" LEGO set.
Most sets are very expensive, I think cheaper set is a good way to follow.
