I am just finishing reading this version:
http://www.amazon.com/Mis%C3%A9rable.../dp/B00AEZT4YO
It's not free, but $2.99 is not much - and it's a long book.
It's also Hapgood. It's illustrated, pleasantly. X-ray enabled (but not much there). I found no typos or formatting problems.
EDIT: opsie, I should have read the whole thread. My recommendation is the same as the one above, by ElspethB
