Massive Ello Creation System Megaload! This is a collection of over 1500 pieces from the original Mattel line. There is approx. 15 lbs of pieces, including pieces from fairytopia, ello-opolis, jungala, and aquaria sets. Comes with a building box set, and 2 smaller platforms on top of the massive amounts of pieces involved. This is the biggest set that I have found on Ebay, and definitely the best bang for your buck if you want everything at once and are ready to start building.
