I am using a long thin plastic box with a lid, in a 'wedge system'.
It took a while to find the right box: The box itself was originally designed as a plastic Christmas tree storage box. It is around a foot wide and deep, and 4ft long. It holds up to about 77L, which is the same as most home systems.
When using it, as for the larger farm scale wedge system, you layer your greens/browns and grit etc from one end at a slope of say 45 degrees. Each week I add my veg scraps and browns on top to make a bigger wedge.
I've not got far yet but the worms are thriving. I keep spare shredded card at the other end of the box to soak up excess moisture (I figure the microbes in that moisture are probably worth recycling into the worm farm)
So far the worms are thriving and happily multiplying. I like the size because it fits neatly in my outhouse (protected from the colder weather) and it is portable if needed (I took it to a horticultural society event to show children the worms - went down very well!)
Once I get to the other end, I'll start harvesting from the start point, and then push the remaining matter along the box to maintain the wedge and carry on adding more organic matter.
This is simple, cheap and accessible - I am so glad I didn't pay money for a more expensive system.
