We've really enjoyed the Yimby 37 Gallon Tumbler Composter. It took less than an hour to assemble with two of us (would have been difficult with one person) and has been working well ever since. It's smaller than I expected so we filled the first half really quickly. We've been trying to go slower on the second half so the first can keep up. The clever detail on the sliding door to tell you which side to add contents to is a nice touch.
