The plastic compost bins sold at garden centers are not strong enough to keep racoons and rats from getting in and making a mess for you to clean up. I use blocks or concrete (cinderblocks) to form three sides and have a wood front and top. That way I just lift the top off to add or mix the compost and the door can be removed to shovel out the compost. Good luck!
Thank you very much. I like the inexpensive approach, and your note about animals getting in has been a concern.
