I finalized editing my personal statement a few months ago and I used a wide variety of resources. I enlisted the help of family, friends, my pre-med advisor, campus tutoring services, and an online editing service. I didn't post mine to SDN for others to read, but you could also go that route I suppose. I shopped around for online editing companies for a while and finally went with Gurufi.com. I picked Brian as my editor only because he had the most amount of stellar reviews, but all the editors seemed very well qualified. Of all my resources, my Gurufi editor was by far the most helpful. It was roughly $100 although rates vary among editors I think. For me, at least, I could justify spending that money if it helps me get into medical school. In short, if you can get a personal statement you're happy with without paying, great. I was satisfied with my statement, by an experienced editor of this topic really made my personal statement stand out. I don't think I'll be missing that $100 in ten years.
