If you have the space, I'd go for 2 containers, so you've got 1 being filled and the other rotting down/ ready to go. In fact I've got 3, one being filled up, one rotting down and one with rotted stuff ready for use. But I an fortunate in having a place where they can go which doesn't impede on my garden space as they are not things of beauty. There are alternatives to the dalek bins, a lot of people favour wooden ones, and if you can get hold of Alys Fowler's 'The Thrifty Gardener', she has instructions for making wooden ones which look like beehives- in fact if you do a google search you will probably find loads of ideas. I tried a wormery once, but didn't really get on with it, and even though I have had a couple of problems with rodents over the years, I find that giving the bins a hefty kick as I pass, and encouraging visitors to do likewise, they haven't returned. Kate's point of how much waste you will be able to source/ generate is also worth taking into consideration.
