Frank, INRAD sells new R-4C AM filters for either $110 or $120 USD. The asking prices for any used filters I have seen for sale are usually in the same vicinity or higher. I also need (want) an AM filter to complete the filter selections in my R-4C. Considering the used prices I will buy a new one from INRAD if I absolutely must have one. They will give you a guarantee that you won't receive from a used item seller.
