A couple of crates and a 1800mm sheet of melamine worked well for me: https://www.flickr.com/x/t/0094009/photos/benrhughes/1082833.... Cost all of about AU$40.

Because I have a corner desk, I can sit at the other half when I want to write, and I use a stool for the rare occasions I want to sit while typing.
