I have read that prices have increased. On the other hand, last few times I looked there were about 3X more lenses for sale than when I was tracking.
My point is that if you are in the ebay racket, it pays to research: I recommend track lens auctions for about a 1 month period before actually bidding.

auction won high = $147 / auction won low = $46 ---> it pays to research!
I noticed knowledgeable sellers as well as sellers who didn't have a clue. Several who bought camera-lens sets then relisted the lens in a new auction, and it worked, selling the lens for more than the set. Deals pop up in strange ways: an auction won for $244 included a 28, 35, 50-1.4A and 105-2.8 all Pentax set from a "retiring amateur". What a set of lenses for a fantastic price!
