I have one, seen VERY LITTLE use, that I am getting ready to list along with the rest of my Canon gear. I'm getting out of photography as I don't get to do enough of it to justify what I have into it. PM me or email me at jcymail3000 (at) yahoo (dot) com. Thanks.
I also have the CPE-4 that I just bought last month and only used it once, if you're interested.
