For me, the Yaz IF card was much tougher to find than the "Rader" card. Recently, I have seen consistent pricing between the Yaz IF and Rader cards. I did find both cards embedded in lots, the Rader by luck and the Yaz IF card knowingly.

My guess would be that 10-15 copies of each the Rader and Yaz IF come up for sale a year via EBAY based on my observations....some copies are listed as the specific variation while others are unknowingly embedded in lots, or as in the Yaz card unknowingly listed as a common.
