We got ours from Camping World on sale for about $50. They are the same as the ones listed above. We bought two to go side by side and they are really wonderful. If it rains, the water goes right threw and when it is time to leave, we just sweep the large stuff off (most of the sand will fall through) and fold and go. We had the green stuff you buy at Home Depot or Lowes but after the last trip we could barely lift it because it was so heavy with sand and water.
