I think the recent fluctuations in currency rates have opened up some interesting possibilities.
I think this DA 40mm brand new can be had for under $210 from Prodigital2000. They never have an open auction on this lens. They usually have it with BuyIt Now price for $249. I think their newer listings are going up in price. This is the last chance to pick up a good deal.

Here's another one from Henry's. I never noticed a DA 70mm at such a low starting bid and such a low BuyItNow price.
