I wish I could tell you where to find one. I discovered them about a year ago and spent nearly 3 months looking before I finally bought one on eBay for $1,400.
Lately, I haven't even seen them on eBay. If you are desperate, you can import the JVC HM-DR10000 from Japan. But, the JVC has issues about staying in "HD" mode (from what I have read casually online).
Just do a search of JVC HM-DR10000, on this forum and you will find a lot of information.
