Nop, sorry. I never had to :( Anyway, I don't think that will be an issue.

I also wander, what would a good English translation consists of? 14th century English? I'm afraid the subtleties related to the language will be lost, in this case, won't they?

And the rest is just mundane stories, which you will appreciate in any language, I'd say.

So, I wouldn't worry. Buy any version and enjoy, as I did, reading about how the world didn't change much in 7 centuries :) (I also find some tales quite funny.)
