I've been using this small Hornady sonic cleaner for the last 2 years. I have about 150 cycles on it now cleaning everything from 223 up to 300winny brass. I'm sure you can find one just as good for cheaper but the size is great for the reloading bench.
Just a tip for better cleaning… I use “hot water” with the Lyman turbo cleaning solution, works better then the Hornady cleaner. Add a drop or 2 of dish soap, and 1oz of vinegar to your cycle and it really improves the cleaning inside the case and primer pocket. 7-8mins cleaning then rinse with clean warm water.
