My sis-in-law has a "stackable" compost bin.  It is in 6 stackable pieces.  The idea is that you can make the sides the height you need and easily raise or lower to turn, move, or use the pile.  I didn't measure it, but each piece is about 6-8 inches high and about 3 feet square.  Each piece is light, so easy to move.  

Please reply with any questions and approx pick up day.  Thanks!
