The system I have experience with and the one that's recommended in Jenkins "Humanure Handbook" is a simple bucket. Spray sawdust on top after use and close the lid. Dump the bucket in compost bin when full, which should happen every 1-2 days in a household with a few people. Barely any smells, no insect problems, cost is very low.
