Like Pete, I use the Toro leaf buckets as well. I have had one base partially crack when I dropped it full of decoys on some slippery rocks when I lost my balance while I was loading a canoe to tow down the shoreline. They've become a bit pricey, but if you continue to search on eBay in the Fall you can usually find some decently priced. I pried the crack open and use a two part glue for plastics (incredibly stinky stuff when mixed, so work outside. I taped the crack on both sides with duct tape and it is holding fine.
I can load 22-25 oversize divers per bag since these are larger than most leaf buckets. The collapsibility is nice when you need to open-up some space in the boat after putting out a hundred decoys.
