i was going to make one at home out of a plastic bin but i came across this today while paroosing target. great design, a little spendy at $99 but i like the three tier design and especially the spout at the bottom to harvest "worm tea". do-it-yourself version doesn't have the option to harvest tea which i really want. the reviews are good on the target website for those that were looking for a vermaculture compost bin.
and speaking of tea....check out the nasty tea video below. got tea on my mind!
