I've looked at the American original of audible.co.uk, and the selection is much better and the prices much lower (not least because a dollar is only worth about 50p these days). But they say they can't offer downloads to the UK - do you think it's worth pretending to be a US-ian? Probably wouldn't work would it, because of my billing address? It's just they've got lots of things I'd like which the British audible don't have. And I don't mean just American books: they've got the Seamus Heaney Beowulf, and two Yeats collections, and the British site doesn't have either.
Anyway, I've just downloaded the Call of Cthulhu, and the complete Shakespeare Sonnets from the Brit site, so I'll see what those are like.
