Pentax Q at 499$
Not sure if the price of the Pentax Q has now settled at 499$, but I've seen it regularly above 549$ lately.
Anyway, Prodigital2000 has it on their ebay store at 499$ with free shipping. I'm not trying to advertise for them or anything, but I did ordered my camera and a lens from them and I must say their service was excellent.
On a side note, I am very tempted to purchase it for my wife so that she can carry it everywhere and take pictures of our first born that we are awaiting in April... mmm, 500$ is still a lot of money!
(I also posted this on the Pentax DSLR forum, sorry for the duplicate).
