Hey I came here looking for info on Canton Smith myself. They are not flagged on P&E, but the link there directs you to this site:
cantonsmithagency.com
which is for an agency called Chamein Canton Literary Agency, which automatically redirected me to the site for the Canton Smith Agency. There are apparently three agents working there: Chamein Canton, James Weil, and Eric Smith. As of this post, they are claiming that their focus is currently on their current clients, but they are willng to accept queries for "women's fiction(chick lit), Latina fiction, African American fiction, multicultural, romance, memoirs, humor, and entertainment, in addition to more nonfictiontitles (cooking, how to, fashion, home improvement, business, etc.)" to any of their gents via email.
I have read alll the other posts on this thread, I have been to their site, and I have no true or factual reasons to suspect them of being anything but professional. That being said, I'll pass for the moment on sendng them my query, and I doubt that even they would blame me. A book is more than a product you have to sell. It's a part of you whose future directly dictates your own. It's not worth it to rush through this proccess just because it's easier than sticking it out and waiting for that dream agent to come along. I'm still looking for mine, and I know that it might not be easy, but I could never risk the future of my book with someone I wasn't 100% sure of.
