As mentioned, epub made by AWP are good, but there is always something that needs to be polished IMO and this is where Sigil can especially be used for.
The latest version (beta) now offers a search regex function (similar to Word I think) which facilitates the cleaning of documents inside AWP.
Anyway, the software can be used for 30 days (trial version) here is a link where you can get it for $ 10.

PS Hope this help, and I don't work for them!
