If you want massive wing area and incredible 3D, definitely have a good look at the PAU Edge.

2123 square inches and 26 pounds with a DA-100. $1000 purchase price gets you the plane with a full hardware package and carbon wing and stab tubes. Great-flying bird! The PAU/BME Ulty is also a great-flying machine and its price is very low for a plane of its size.
