EBay's your best bet. I haven't seen them anywhere else.
A couple of options here.
I'll see if I can dig one out and get it listed on eBay later today. Typically I only sell parts on eBay to keep my life simple as far as accounting stuff & record keeping for IRS.
I didn't find one today but I know I have some around. In the next day or two I'll get one listed then PM you with an item number. As far as condition I am sure I'll have one that is fairly nice. I can't say perfect or anything until I have it in my hands but it will be a good usable part with no major issues 100% for sure. Pictures will tell the story once I have it listed.
