This is the compost bin I want to get soon.... hope you are reading this Ken. If you are interested in how to make it - dead, dead simple - go and have a look here: http://www.gardenorganic.org.uk/factsheets/gg24.php
It is the best of designs because it isn't fixed anywhere and could be moved to another position easily. Each section is light enough to lift on and off. You build the height of the bin section by section as you fill it so no having to lob stuff over the side of a tall bin until you need to, even better the reverse is true - as you take out the compost to use you can take off a section of wood so, again, you are not having to shovel stuff up from the bottom of a three foot deep bin. You can make it the height to suit yourself. You can run two bins (which is the ideal) and by sharing the pieces it is unlikely you will need to build enough sections for two complete bins. It is likely while the contents of one are being used up, the other is being made. If you can get hold of some old floorboards or an old pallet cheaply it shouldn't cost much.
You don't have to have a bin to compost but it is easier and there are a zillion ways to make one. Also just mounding stuff on the ground doesn't create the same amount of heat for a lot of the stuff as it will if squished into a confined space. Four hefty posts hammered into the ground and wrapped round with chicken wire is perhaps the simplest.
If you don't know about composting there is a ton of stuff on the web. You could start here:
I really recommend you consider it other wise you will have a ton of rubbish to cart of somewhere at the end of the growing season and that is such a shame because it is pure gold for growing your own and costs nothing once the bin is made. I am a control freak and would like my own bin so I know what's in it as I am only growing stuff to eat and I don't use any chemical controls. Also a domestic small compost bin won't kill some perrrenial weeds or weed seeds so I'd rather avoid compost with those in it. It matters less if you are growing flowers of course and you don't mind a bit of weeding. I found our shredded office paper made good brown waste. I have left a little pile of soil and weeds on some cardboard at the lotty until I can get a bin to put it in, so don't worry about it being the beginning of an eyesore, it will end up in a bin soon(ish).
