What are you looking to spend? You mention here you need cheap but durable. You mention later that you need high quality and waterproof.

So high quality, waterproof, durable, and cheap? You cant get the first three while also getting the last. But 'cheap' is relative. So list a total you would want to spend and what size you need and you will get some better specifics since as of now, you have gotten everything from kitty litter plastic boxes to Ortliebs. Thats basically the full spectrum of options.
