I just bought the Sony A100K, 10.2 MP with the 18-75 mm sony lens but went with the TAMRON 70-300mm lens also. Just waiting for it to get here so I can try it out. Pretty impressed by all the reviews I have read and went to the store and played with all the comparable cameras and was most impressed by the Sony. I do mainly everything full manual but was very impressed by the turn-up speed and the auto-focus speed. Very fast.  And I like the stabilization being in the body rather than the lenses. Now we will have to see if it lives up to the hype!
