SainSmart has them, but pulled the old switcheroo on me. I ordered 25 of the Type II that I need and they were advertised at $12.73. I got them down to $12 for 25. They then informed me that the shipment was delayed. Later I got a shipment statement with their part number. I went to their site to compare the number with my order and discovered that the part number was for a Type I, which wasn't even on the page before. The Type II was also listed on the page, but for $23. I raised Holy Hell and they said they would "fix it". I don't know what that means yet, but will let you know what I've found out.

One of my User Group members (SoftwareControlHamRadio) is making a PCB that takes a Type I and fits it into the Type II mount configuration. After he reports back, I post his contact info here. He feels it will be under $2 for the adapter. We'll see.
