I'd be willing to give 'em a look too. I personally LOVED writing mine and thought it was the most fun part of the process.
And FYI, I am already accepted and have picked a school and thus will gain no benefit from reading any of your essays. If you'd like to read mine I'd be glad to share, as I'm sure NONE of you would have an at-all-similar PS as me. And forget about us goons on SDN, have some profs read it too. I had most of my LOR profs read it and give me input which was probably the most helpful of all.
Two words of advice tho. BE ORIGINAL!! The PS should be the part of your app that makes you recognizable. The adcom sees 1000's of #'s (GPA + DAT) but a great PS can really get lodged in their head and really give you an edge, as will a stellar interview. I got this right out of the mouth of the chairs of three stellar d-schools that loved my PS, so don't think I'm making this up.
Anyways, good luck with the apps and take my advice, APPLY EARLY. I'd have saved some gray hairs and big cash in deposits had I done that.
