Hello everyone, how are you guys doing today?
I am a new member here. Nice to meet all the members here.
Now, I need you suggestions/advices/opinions about the used Digital Cameras.
I found these 6 digital cameras on amazon which fit my budget, but I dont know which one I should buy. I believe that you guys can help me with this:

1. Canon PowerShot Pro Series S5IS2. Panasonic Lumix DMC-FZ18K

3. Sony Cyber-shot DSCH50
4. Sony Cybershot DSC-H9
5. Fujifilm Finepix S9100
6. Fujifilm Finepix S9000

I want to purchase one of these digital cameras to learn the basic about photography. Do you guys think that these cameras are suitable for my purpose? Or do you have any other suggestions or ideas for me?

Most of the pictures I am gonna take are portrait, landscape, motorcycle ( I have a sport-bike, and I often ride with my friends at night. ), indoor, and macro. In addition, I rarely take sport/motion pictures.
I am looking forward to receive your replies.
Thank you in advance.
Have a good day.
