"Classics" doesn't mean translated, as far as I know... unless you mean old Greek and Roman authors. But if Don Quixote is a classic, then Shakespeare is classic too, and it's not translated (into English).
New translations or editions would be welcome. I'm very suspicious of public-domain works offered for sale at very low prices... I feel most of them are direct conversions of Project Gutenberg versions, with no care with formatting or proofreading.
