I just purchased an A610 to replace my old Fuji 2.1 MP.
I got the A610 for $220 shipped, including tax to CA from Dell last week.
I like it better than the SD series. I think they are too small. Using a slow shutter speed, I think you'll get more blur from the SDs than the A series. I really liked the 4x zoom. I like the 4AA batteries. Buy four good rechargable batteries, keep a set of alkalines around as a spare, and you're good to go.
