Hi Bob... as you are aware, I have been keeping up with the Fresnels closely since they first reared their pretty head on eBay. Since early November 2000, over 70 Fresnels have been sold on eBay, the highest selling for $292.50 and lowest so far at $100.00. It has been a rush from the very beginning as the "Fresnel Frenzy" hit the market. Now that it has slowed to a snail's pace, and some diligent collectors are finding them on shelves, value is tapering. Like anything else, I'm sure their worth will rise a bit in the future, albeit slowly.
