I am a fan of Joe Jenkins and his sawdust toilet informational crusade. I am a strong DIY person and generally short on money so I have gone the cheap route and made my frame from scrap wood and plywood and scrounged pails from a bakery but I recognize that the world is filled with all varieties of people. If someone did want to get started with everything one needs to have a sawdust toilet up and running except the sawdust and the compost area you can buy a kit from The Humanure Handbook site. I recently had a fresh look at their store and realized that they have revamped the toilet frame to IKEA style construction, allen key provided. As with IKEA assembly is required, although it looks very simple in the how to video. Joe provides free plans for the original style frame but started making kits at the request of pIeople who would rather spend the money and have a sure fire set up. To each his own, I am happy with my system and I have gathered enough materials for at least two more but I must admit the Jenkins kit frames are very pretty and would provide people with a fast almost turn key set up.
Life is too short or my list is too long, not sure which.
