You can make these for under $100 without cradles, $200 with. They work GREAT on hard and soft sand, just not to well on uneven ground. DON'T put the extra holes in them and use butter tops for washers. Put some silicone around the washers and connectors. You can find the barrels http://www.stores.yahoo.com/baytec/30galfoodgra.html
