Not to add to the confusion but...
I picked up the Sony Alpha and dig it. The main reason for me choosing this camera over others (Nikon D40) is that the others have the "anti-shake" built into the lenses. This causes the lens to be incredibly expense.
With the Sony, the anti-shake is built into the body, so old Minolta lens work just fine (I had a bunch from my old camera but you can find them on Ebay as well).
I hope this helps
