I am seriously wondering whether it's worth it to have a professional editor review my novel prior to querying agents. There are plenty of editors out there offering help for a fee, and I am not one to deny that their time and experience are worth their hire. But I can't help wondering whether I'd regret the expense later, assuming I can even come up with it.
What is a better use of my (hypothetical) writing funds... editing, or a laptop of my own?
Has anyone had personal experience with any of these services?
