Vremi Tumbling Outdoor Compost Bin – Dual Chamber 360° UV Proof and Rust Proof 42 gal with Secure Sliding Doors – All Season Composter with Aeration System – $40.49

This and other units like it are typically at least $80. They seem to be overstocked and discounting quite a bit. These take some time to put together, but make it easy to compost.
