A friend asked how much a new 160a would cost - after listening to me brag about mine. I did a search on the camera name and there are a few online retailers selling the 160a for $2500 to $2700 with free shipping and a one year warranty. These are advertised as brand new and come with a one week return policy. Is this the start of a price drop or is there something else about these that I should be aware of?
