摄影沙龙 is really great! Thank you all for your help.

Thank you all for your help.  I have just ordered an Olympus Pen E-Pl1 at amazon.com for $499.70.  I have also ordered three books:

Olymbus Pen E-Pl1 for Dummies, $19.79

Digital Photography for Dummies, $16.49

Understanding Exposure: How to Shoot Great Photographs with Any Camera, $14.49

This should be a good packet for any beginner, I guess.

I greatly appreciate the advices I got from here.  I will study and practice immediately after I get my new camera and the books. I am also plan to buy a Canon DSLR camera later.  

From the bottom of my heart, let me say “Thank You!.” 摄影沙龙 is really great!
