I've tried contacting Jackson Labs a few times, both through the form on their website and via email to purchase, but haven't heard back yet. They look like really nice units, and I need one to replace a "Pentar SA101" (a Furuno on an adaptor) in my Symmetricom S250. It looks like Synergy GPS also still sells a M12M compatible board, but their lead time is 20 - 30 weeks.

I called the number on the website and they called me back. They are Las Vegas time so it was later on the day for me to call since I am EST. I believe that it was $399.00 per unit. It mounted in my S300 perfectly. The only issue was that the board is close enough to the PS that I couldn't leave a USB cable plugged in. If I ever to reprogram it, I will have to take it out. In my case, I wanted a slightly different config so I programed it before I installed it. The lead time was just a couple of weeks.
