Editing suspense fiction

Is editing fiction more difficult than writing it?

Maybe it doesn't take as long as writing a novel but for me it's a source of frustration. My editing processes these days involve a few key people with writing and reading skills to go over my work after I have already done so countless times. I really can't afford to spend hundreds of dollars (or more) on 2 or 3 different editors.

Then after getting their feedback and corrections I read it again myself at least 3 more times. I enlarge the print to 300% - I find this helpful in seeing typos and grammar errors more easily. There comes a time when you have to say enough is enough and stop reading it anymore. Sometime later someone will inevitably find a typo and point it out, but hey... I find typos and errors in almost every book I read so best  be happy and settle for 99% accuracy in editing.

Happy fiction writing! If anyone has any tips on self-editing please share. Thanks.
