A couple of ideas for a worm composter bin

Worm Factory 360 Worm Composter

Worm Factory 360 WF360B is one of the best products of Worm Factory. It ships with four trays but you can extend it up to 8 trays. This makes this model the larges ready to use home style worm composter. One of the advantages of the Worm Factory 360 is that it comes with an starters’ DVD, and an accessory kit with some bedding and simple tools included. If you are a true novice this bin makes your life easier.  It is a little on the bulkier side and while its high posts makes it convenient to work with it while you are standing they also make it more difficult to store it in tight places (such as under a sink, or a kitchen cupboard). The picture on the left is a black bin it also comes in green and terra cotta. Overall this is one of the better deals out there if you are shopping for a worm composting bin.

Worm Factory DS5TT 5-Tray Worm Composter

This  Worm Factory DS5TT 5-Tray is a true monster. It comes with 5 trays already in place. You can safely add another two. In my opinion it is good for those who would start big. It is 2 inches smaller in length and width than the360 and it has shorter support legs. This means that you will be bending when you are working with the lower trays but at the same time smaller dimensions and lower height means you can put it into a tight space. It comes with a manual and how to guide but no DVD. Since additional trays are also available you might consider Worm Factory DS3GT 3-Tray Worm Composter . Which is essentially the same product only it ships with three trays instead of 5. This means you can actually stash it under something in your garage or kitchen. And in case you decide to build up you can always purchase individual trays.
