Most knowledgeable authors don't recommend going without editing at all. They may substitute an editor for peer editing by fellow authors they trust, but it's still editing by a second set of eyes.

I know of no author who can single handily turn in something that doesn't need some grammar/spelling/etc correction help. The writer is simply too close to the work to see some of them, though there are tricks to help like having text-to-speech read the item back to you.
